Based on all 721 Steam reviews in every language. Median playtime in a sample of 289 reviews: 3h for positive, 0.8h 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.
