Names come from each game’s Steam store page. Spellings that differ only in capitals, accents or punctuation share a page.

Games are matched by the developer and publisher names on their Steam store pages; names that differ only in capitals, accents or punctuation count as one company. Players now is the sum of each game's latest poll. The share positive weights each game by its number of reviews, so the biggest games count most; the middle game's score counts every game with at least 10 reviews equally. Monthly players are the sum of each game's average for the month, from the archive before October 2026 and our own polls since. A year's reviews are every review the games released that year have had, up to today.
