These games: The similar games share Action Roguelike (8 of 8) and Rogue-like (5 of 8).
The winners: Winners here lead with Action Roguelike + Rogue-like, priced around $15. The breakout hits carry Replay Value + Pixel Graphics + Great Soundtrack; 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
