Problem Definition
GameForge is an independent mobile gaming studio generating $65 million in annual revenue, virtually all of it from CastleClash, a free-to-play strategy game launched four years ago. At its peak two years ago, CastleClash had 20 million monthly active users and was the top-grossing strategy game on both iOS and Android. Since then, monthly active users have dropped to 12 million, and revenue has declined roughly 15% per year.
The studio's leadership team has identified four potential paths forward: investing $15 million in a major CastleClash expansion featuring new game modes and social features; spending $20 million over 18 months to develop an entirely new original game; acquiring a smaller studio with a growing title for $25–35 million; or pivoting the business model to become a live-service publisher for third-party developers. GameForge has $40 million in cash on its balance sheet.
The board of directors has set a clear mandate: present a credible path back to revenue growth within two years. Which option should GameForge pursue, and why?
Additional InformationAsk for more dataHide data
- CastleClash is a free-to-play strategy game monetized through in-app purchases and a seasonal battle pass
- The mobile gaming market is growing 8% annually, driven by emerging markets and mid-core genres
- GameForge employs 180 people, with 120 dedicated to CastleClash live operations
- Industry benchmark for successful game expansion ROI is 1.5–3.0x
- New mobile game success rate (defined as recouping development costs within 2 years) is approximately 15%
- The studio has never acquired another company and has no M&A experience
Question 1Structuring
Prompt: "How would you structure your analysis to determine which of the four growth options GameForge should pursue?"
Hint · Structuring
Build 3–4 branches that are specific to this client and question, not a generic framework. Check they don't overlap and together cover the problem.
Additional InformationAsk for more dataHide data
Provide the candidate with the four options if they do not recall them. Allow 3–4 minutes for structuring. Push back if the framework is overly generic (e.g., a pure profitability tree with no gaming-specific dimensions).
What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate organizes analysis into three or four standard buckets — financial attractiveness, strategic fit, risk, and feasibility — and applies them generically to each option. Covers the basics but does not tailor the framework to gaming-specific dynamics or the studio's constraints.
- Level 1: We should compare the options on cost, return, and risk.
- Level 2: The comparison needs to account for GameForge's specific situation — limited cash, no M&A experience, 2-year timeline.
- Level 3: Use the constraints as hard filters to eliminate options before doing deeper analysis on the survivors.
Strong (4): Candidate customizes the framework to the gaming context with dimensions such as:
- Time to Impact — Can the option deliver measurable growth within the board's 2-year mandate?
- Expansion: ~6 months to launch
- New game: 18+ months to launch, unknown ramp period
- Acquisition: 3–6 months to close, integration risk adds delay
- Publishing pivot: 12+ months to build pipeline and sign developers
- Risk-Adjusted Return — Expected value weighted by probability of success
- Expansion leverages existing audience and infrastructure
- New game carries a ~15% industry base rate for success
- Acquisition depends on target quality and integration execution
- Capability Fit — Does GameForge have the talent and experience to execute?
- Strong live-operations team (120 people) favors expansion
- No M&A experience makes acquisition risky; no publishing infrastructure makes the pivot slow
- Reversibility — What happens if the chosen option fails?
- Expansion: $15M at risk, but the team and codebase remain intact
- New game: $20M sunk, 18 months of opportunity cost
- Acquisition: $25–35M locked up, cultural integration risk
Excellent (5): Adds two additional dimensions beyond the strong answer. First, optionality: the expansion, if successful, generates cash flow and buys time to pursue a second option later — it is not mutually exclusive with the other paths. A candidate who recognizes that options can be sequenced rather than chosen in isolation demonstrates strategic maturity. Second, talent retention: 120 engineers working on a declining game may leave if they do not see a credible growth path, which would undermine the execution of any option — this is a hidden constraint that most candidates miss because it does not appear in the financial data. The candidate also considers competitive timing — whether rival studios are launching competing titles that could narrow the window for a CastleClash expansion or make specific acquisition targets more expensive.
The candidate might also propose using the 2-year mandate itself as an elimination filter: any option that cannot demonstrate measurable progress within 12 months should be deprioritized, which immediately weakens the case for the new game (18-month dev cycle) and the publishing pivot (requires building an entirely new capability).
Question 2Numeracy
Prompt: "Let's compare the expansion and new game options quantitatively. I'll give you some probability estimates from the product team. Calculate the expected annual incremental revenue and simple payback period for each."
Hint · Numeracy
Write the formula before you plug in numbers, keep units and zeros explicit, and sanity-check the order of magnitude at the end.

Step-by-Step Solution
Option A — Expected Annual Incremental Revenue:
| Scenario | Probability | Revenue Calculation | Weighted Revenue |
|---|---|---|---|
| Base case | 60% | 4M users x $5 ARPU = $20M | 0.60 x $20M = $12.0M |
| Downside | 40% | 1M users x $5 ARPU = $5M | 0.40 x $5M = $2.0M |
| Total expected annual incremental revenue | $14.0M |
Simple payback period = $15M / $14M/year = ~1.1 years (~13 months)
Option B — Expected Annual Revenue:
| Scenario | Probability | Annual Revenue | Weighted Revenue |
|---|---|---|---|
| Hit | 15% | $50M | 0.15 x $50M = $7.5M |
| Moderate | 25% | $10M | 0.25 x $10M = $2.5M |
| Failure | 60% | $0 | 0.60 x $0 = $0 |
| Total expected annual revenue | $10.0M |
Simple payback period = $20M / $10M/year = 2.0 years
Note: Option B also requires 18 months of development before any revenue, so total time to payback is effectively 3.5 years from the investment decision.
Comparison Summary:
| Metric | Expansion (A) | New Game (B) |
|---|---|---|
| Investment required | $15M | $20M |
| Expected annual revenue | $14M | $10M |
| Simple payback | ~1.1 years | 2.0 years (3.5 incl. dev) |
| Probability of positive return | 100% | 40% |
| Maximum annual upside | $20M | $50M |
What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate calculates expected values correctly for both options and identifies that Option A has better risk-adjusted returns and a faster payback.
Strong (4): Candidate also notes that Option A has a 100% probability of generating positive revenue (even the downside case produces $5M/year), while Option B has a 60% chance of total loss. Flags that the payback comparison understates Option B's disadvantage because 18 months of development produce zero revenue.
Excellent (5): Candidate observes that while Option A dominates on expected value and payback, Option B's hit scenario ($50M/year) would transform GameForge into a multi-title studio — a qualitatively different strategic outcome. The candidate frames this as a risk appetite question rather than a pure math question: Option A is the rational choice for a board demanding 2-year results, but a sequenced portfolio approach — launch the expansion now, then fund a new title from expansion cash flows in 12 months — could capture both the near-term safety of A and the long-term upside of B.
Reality Check: A $5 annual ARPU (~$0.45/month) is realistic for a mid-core free-to-play strategy game. Top-grossing strategy titles achieve $8–15 annually, while casual games average $2–4. The probability estimates align with industry data: major expansions for games with healthy engagement typically have high success rates, while new title launches average around 15%.
Question 3Judgement & Insights
Prompt: "Take a look at Exhibits 1 through 3. Based on this data, how would you assess the expansion option's likelihood of success? And if GameForge were to pursue an acquisition instead, which target would you recommend?"
Hint · Judgement & Insights
Read the exhibit title, axes and units first. Lead with the ‘so what’, then back it with one or two numbers.

What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate notes that CastleClash revenue is declining and MAU is dropping, raising legitimate concerns about expansion viability. For the acquisition, selects NeonByte based on its highest growth rate (+60%) and lowest price-to-revenue multiple (2.0x).
- Level 1: Revenue is declining 15% annually, which makes expansion risky.
- Level 2: But the cause of the decline matters — is it a product problem or a natural churn problem?
- Level 3: If we can diagnose the root cause, we can assess whether the expansion addresses it.
Strong (4): Candidate identifies the DAU/MAU improvement from 25% to 35% as a critical hidden signal. Recognizes that the revenue decline is driven by player count erosion, not deteriorating engagement — the remaining 12M users are actually more engaged than ever. Average session time has nearly doubled from 18 to 30 minutes. This means the expansion would target a healthy, engaged core rather than attempt to revive a dying product. On acquisitions, the candidate flags NeonByte's unusually low DAU/MAU (18%, below the 20% industry average from Exhibit 3) as a warning sign that its 60% growth may be marketing-driven rather than organic.
Excellent (5): Candidate connects insights across all three exhibits to build a layered argument:
-
Engagement-monetization gap — CastleClash's engagement metrics (DAU/MAU: 35%, session time: 30 min, D30 retention: 22%) are all top-quartile or above per Exhibit 3, yet its monthly ARPU ($0.45) is below the industry average ($0.50) and far below top-quartile ($1.50). This gap means the expansion has dual upside: recovering churned users AND improving monetization of the highly engaged core.
-
Quarterly ARPU is rising — Revenue per MAU increased from $1.00/quarter (Q1 '24: $20M / 20M) to $1.25/quarter (Q4 '25: $15M / 12M), a 25% improvement. The remaining users are spending more per person, confirming strong willingness to pay.
-
Acquisition red flags — NeonByte's 18% DAU/MAU combined with 60% revenue growth suggests heavy user-acquisition spending that inflates the topline but does not build a sticky user base. TileWorks has exceptional stickiness (40% DAU/MAU) but only 5% growth, indicating a mature product with limited upside — acquiring it would essentially replicate the maturity problem GameForge already has. PixelForge (22% DAU/MAU, 45% growth) has the healthiest engagement-to-growth ratio, but at $35M it would consume nearly all of GameForge's $40M cash reserve, leaving no buffer for integration costs or other strategic bets.
-
The hidden price-to-revenue trap — NeonByte at 2.0x revenue looks cheapest, but TileWorks at 1.4x ($25M / $18M) is actually the lowest multiple. However, multiples on barely-growing revenue are misleading — what matters is the forward multiple adjusted for sustainable growth, which favors PixelForge despite its higher sticker price.
Question 4Synthesis
Prompt: "The CEO has five minutes before the board meeting. What should GameForge do?"
Hint · Synthesis
Answer first: the recommendation, two or three reasons with numbers, then risks and next steps.
What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate recommends the expansion with basic rationale — best risk-adjusted return, fastest payback, stays within budget.
Strong (4): Candidate delivers a structured recommendation:
- Primary move: Invest $15M in the CastleClash expansion. The data shows the game's core is healthier than the headline revenue decline suggests — engagement metrics are top-quartile and improving. Expected payback is approximately 13 months with 100% probability of positive return.
- Secondary move: Use expansion-generated cash flows to fund a new title ($20M) starting in 12 months, creating a sequenced portfolio approach that captures near-term stability and long-term upside.
- Key risk and mitigation: The expansion must launch within 6 months to demonstrate results within the board's 2-year window. Set quarterly milestones tied to MAU recovery and ARPU improvement. If MAU does not recover by at least 2M users within 6 months of launch, reassess.
Excellent (5): Candidate adds a monetization angle and a specific contingency plan:
- Monetization unlock: CastleClash's ARPU is 70% below top-quartile benchmarks despite top-quartile engagement. The expansion should include new monetization features — premium social features, guild subscriptions, a cosmetic marketplace — not just new content. Even a modest monthly ARPU increase from $0.45 to $0.75 would generate $0.30 x 12M existing users x 12 months = $43M in incremental annual revenue from the current base alone, before counting any recovered users.
- Contingency: If the expansion fails to recover at least 2M MAU within 6 months of launch, pivot $25M toward acquiring PixelForge (strongest engagement-to-growth ratio among the targets) while GameForge still has cash runway.
- What to avoid and why: The new game option ($20M, 60% failure rate, 18-month delay) and the publishing pivot (no existing capabilities, 12+ month ramp) are both too slow and too risky for a 2-year mandate. These become viable only after the core business stabilizes.
- One-sentence board pitch: "CastleClash has a top-quartile engaged audience that we are under-monetizing — the expansion unlocks that value in 6 months, pays for itself in 13, and funds our next bet."

Exhibit Insight Guide (Interviewer Reference Only)
Exhibit 1 — CastleClash Quarterly Performance
| Insight Tier | What to See | Why It Matters |
|---|---|---|
| Level 1 (Surface) | MAU declining from 20M to 12M; revenue declining from $20M to $15M quarterly | Establishes the problem — the game is losing players |
| Level 2 (Hidden) | DAU/MAU rising from 25% to 35%; session time rising from 18 to 30 min; quarterly revenue/MAU rising from $1.00 to $1.25 | The core is healthier than the headline suggests — churn is among casual users, not the engaged base. Remaining users are stickier and spend more per person. |
Exhibit 2 — Potential Acquisition Targets
| Insight Tier | What to See | Why It Matters |
|---|---|---|
| Level 1 (Surface) | NeonByte has highest growth (+60%) and lowest price/revenue (2.0x) — appears to be the best deal | Draws candidates toward the trap |
| Level 2 (Hidden) | NeonByte's 18% DAU/MAU is below industry average (20%), suggesting marketing-inflated growth. TileWorks is actually cheapest on price/revenue (1.4x) but barely growing. PixelForge has healthiest fundamentals but costs the most. | No target is a clear winner — each has a tradeoff, and the best candidate identifies this tension |
Exhibit 3 — Mobile Gaming Industry Benchmarks
| Insight Tier | What to See | Why It Matters |
|---|---|---|
| Level 1 (Surface) | CastleClash exceeds top quartile on engagement metrics | Confirms the game is not dying |
| Level 2 (Hidden) | CastleClash ARPU ($0.45) is below average ($0.50) despite top-quartile engagement — a massive monetization gap that an expansion could close | This is the single most important insight in the case: engagement without monetization = untapped value |
