What the data shows
- In the first 2 hours 1 in 3 reviews are negative (34%); after 15h it's 1 in 7 (15%).
- Fully opens up by hour 15.
- The game has no story achievements, so drop-off points can't be measured.
- Only 63% of owners have even the first achievement — the rest barely played.

before it gets good opening up fully opened up
Based on all 18,931 Steam reviews in every language. Median playtime in a sample of 297 reviews: 27.3h for positive, 15.1h 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.
