When it gets good

Share of positive reviews by how many hours the reviewer had played when writing the review.

before it gets good opening up fully opened up

Based on all 441 Steam reviews in every language. Median playtime in a sample of 294 reviews: 1.3h for positive, 0.6h 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

Share of players who started the game and reached each story milestone. 100% is the most common achievement (24.3% of owners), so people who bought the game and never launched it don't count.
