We read 85,000 Steam games the way designers do: mechanics instead of genres. Which mechanics carry a game, how they wire together, and what that means in money. Open catalog and research at steammaho.com

I compared 1,430 Steam demos with the full games that followed. A demo with many reviews means a bigger launch. It says nothing about whether players will like the game: there it is a coin flip. The demo's score tells you that, even with 10 reviews. #steam #gamedev #indiedev

Steam reviewers do not mind dying. Games where players say they could see why they failed: 7 points more positive reviews than games like them. Games where deaths come out of nowhere: about the same. Games where the dice get the blame: 1 point more. 1,374 games. #gamedev #gamedesign #steam

Reviewers do not mind dying (gravestones)

Every year about 250 unknown devs break through on Steam (1,000+ reviews). Same in 2016, same in 2025. Five times as many try now, so the odds went from 1 in 10 to 1 in 44. A liked game by an unknown: 1 in 3 made it in 2015, 1 in 10 in 2025. #steam #gamedev #indiedev

Epic says a free week on its store lifts a game's Steam peak by 40%. Across 470 giveaways since 2018, the typical game gained 10% that month, and 4 in 10 had a lower Steam peak than usual. Games with 5,000+ Steam players: +1%. Epic's 40% is the average, pulled up by a few. #epicgames #steam

Horror launches on Steam almost double in October: about 310 a year, against about 170 in other months (2022 to 2025). October horror games reach 100 reviews a little less often: 22 in 100, against 24 in other months. This October so far: 291, up from 268 last year. #horror #halloween #gamedev

Steam reviews get a little harsher after launch. The typical game is 86% positive in its first two months and 84% over the rest of its first year. 3 in 10 games drop 5+ points. Of 74 games that started under 40% positive, 60 went up 5+ points. #gamedev #steam #indiedev

Launch reviews are a little kinder (chalkboard)

Three in four paid Steam games launch with a discount, usually 15% off. That is 77% of 11,391 games released January 2024 to June 2025 with 10+ reviews. Games that went on to 10,000+ reviews: only half did. The next sale came about 50 days after launch. #gamedev #steam #indiedev

Most paid games launch on sale (sale sticker)

Of paid Steam games released January to June 2026, 12 in 100 priced $15 to $19.99 have passed 1,000 reviews. At $20 to $29.99 it is 25 in 100, twice as many. Under $5: 1 in 200. This is not price alone: games at $20 and up are usually bigger productions. #gamedev #steam #indiedev

The $20 line: games past 1,000 reviews by price (price tags)

Steam got 76% more new games this September than last September. August: +40%. October so far: +55%. From January to May the gap was 10%. Most of the extra games come from developers with a single release. A release weekday now has about 110 new games, up from 75. #steam #gamedev #indiedev
