Aggregated over 15,313 stored reviews from 391 games.
Reviews are shown as published on Steam, including reviews from key activations and free copies — so percentages here can differ from the score on the Steam store page. GameTrend does not check whether reviewers bought or played the game.
The top 5 games hold 59% of the niche's 269,394 reviews; it takes 37 games to reach 80%. Fewer games to 80% means a harder niche to be seen in.
