Your set: Your set clusters on Anime (6 of 8) and 2.5D (4 of 8).
The winners: Winners here lead with Fighting + 2D Fighter, priced around $40. The breakout hits carry Arcade + Lore-Rich + PvP; a typical game here doesn't.

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
