Class is the observed scale of a publisher’s portfolio: the median review count of what they released over the last 36 months. Budgets are invisible to us, so these are not the industry’s AAA and AA labels.Peak players is the highest concurrent count since release. “Kept at 5w” compares the fifth week against the first-week peak, counting only releases with at least 20 concurrent players.Concurrent players are observed from 2026-07-19 onward. Releases before that date have no player columns, and that is a gap in our watching, not a zero.
