What the data shows
- In the first 2 hours 1 in 3 reviews are negative (35%); after 10h it's 1 in 30 (3%).
- Fully opens up by hour 10.
- The game has no story achievements, so drop-off points can't be measured.
- Only 42% of owners have even the first achievement — the rest barely played.

Based on all 7,001 Steam reviews in every language. Median playtime in a sample of 296 reviews: 24.4h for positive, 4.5h for negative. Almost every game is rated lower in the first 2–3 hours: that window includes refunds and quick first impressions. What matters is how deep the dip is and how fast the game recovers.
Where players quit
