The peer group is this site's catalogue, not all of Steam. Categories are filled top-down by review count, so the comparison is against games that sold rather than against every release — a percentile here is a harder test than the same percentile across the whole store would be.
About
Forbidden Solitaire is a card-slashing horror game about unearthing the contents of a cryptic 1995 CD-ROM that should have never existed. From the creators of Ancient Enemy and Home Safety Hotline.
