The best-reviewed games on Steam are the ones you play alone

“Big games just get review-bombed.” They don’t — bigger games score higher. Games with 200–1k reviews average 69.6% positive; games with 100k+ average 87.2%. If popularity dragged scores down, competitive games would look bad for a reason that has nothing to do with being competitive. The opposite is true, which makes the gap harder to explain away, not easier.

“It’s really about free-to-play.” Only slightly. Free games average 80.9% across 202 games, paid ones 84.8% across 2,340 — a gap of about 3.9 points, against the 23.9-point spread between the best and worst tags. Free-to-play is part of the story, nowhere near all of it.

Every game on Steam carries community tags voted on by players. For each tag we take every game carrying it with at least 200 reviews, and average the share of reviews that are positive. The sample is 7,222 games.

The tags on the ladder were picked before the numbers were looked at — they are simply the tags that place a game somewhere between “played alone” and “played against other people”. Choosing them afterwards would guarantee a clean line and prove nothing.

This measures association, not cause. Competitive games are harder to balance, live longer, change more, and attract players who keep score — any of which could drive the gap. What the data shows is that the gap is large, consistent, and survives the two obvious alternative explanations above.
