before it gets good opening up fully opened up
Based on all 9,608 Steam reviews in every language. Median playtime in a sample of 299 reviews: 40.3h for positive, 4.2h 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.
