• Total Users: 1,007
• ARPU: $10.86

Interpretation:

• Excellent ARPU: $10.86 per user is strong for a free-to-play game (typical range: $1-5 for casual games, $5-15 for mid-core)
• Above Market Average: This ARPU indicates successful monetization design with appropriate pricing and offers
• Revenue Scale: With current user base, game generates ~$11K annually; scaling to 10,000 users would yield $108K/year
• Balanced Monetization: ARPU reflects healthy mix of spenders across price points, not over-reliance on whales
• Growth Opportunity: With 51.5% conversion rate, focus on increasing ARPPU rather than conversion (already maxed out)

4.2 ARPPU (Average Revenue Per Paying User)

Results:

• Paying Users: 519 (51.5% of total)
• ARPPU: $21.07
• Average Purchases Per Paying User: 2.45 purchases (1,272 purchases ÷ 519 payers)

Interpretation:

• Solid ARPPU: $21.07 per paying user indicates healthy monetization depth
• ARPPU/ARPU Ratio: 1.94x (ARPPU $21.07 / ARPU $10.86) is reasonable given 51.5% conversion - paying users spend about 2x the average
• Multi-Purchase Behavior: 2.45 purchases per payer shows repeat purchase behavior, not just one-time buyers
• Monetization Balance: ARPPU isn't extremely high (not whale-dependent), indicating broad monetization across player base
• Opportunity: ARPPU has room to grow - consider loyalty programs, bundles, or higher-tier items to increase spending per payer

4.3 Conversion Rate

Results:

• Conversion Rate: 51.5%
• Paying Users: 519
• Non-Paying Users: 488

Benchmark: Typical free-to-play conversion: 2-5%

9. Limitations & Future Work

9.1 Study Limitations

• Simulated Data: Data generated by Unity Simulator, not real players - behavior patterns may be idealized
• Sample Size: While 1,007 users is substantial, certain country/age combinations have small samples (e.g., Suriname with 9 users)
• Time Period: One year (2022) provides good longitudinal data but may miss long-term trends or seasonal patterns
• Missing Variables: No information on player device type, acquisition channel, in-game behavioral metrics (levels completed, time-to-first-purchase, etc.)
• Retention Calculation: D7 retention measured as "returned within 7 days" rather than cohort-based day-by-day tracking
• External Validity: Findings reflect this specific game's design; may not generalize to other game genres or monetization models

9.2 Recommendations for Future Analysis

1. Deeper Retention Cohorts: Track D14, D30, D60, D90 retention to understand long-term user lifecycle
2. User Segmentation: Cluster analysis to identify player archetypes (whales: top 10% spenders, engaged non-payers, etc.)
3. Predictive Modeling: Build LTV prediction models based on first-week behavior to optimize UA targeting
4. A/B Testing Framework: Set up controlled experiments for pricing, onboarding variations, feature tests
5. Real-Time Dashboards: Automate KPI monitoring with daily updates using R/Shiny or Tableau integration
6. Churn Analysis: Deep-dive on the 34.4% who churned - identify common patterns in first-session behavior
7. Purchase Timing Analysis: Map when in user lifecycle purchases occur to optimize monetization triggers
8. Device & Platform Segmentation: If data becomes available, analyze iOS vs. Android monetization differences
9. Cohort-Based Revenue: Track revenue per registration cohort to measure improvement over time
