No revenue estimate for EPIC — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $2.3M — a different platform, not this one.

Legend of Grimrock 2

A dungeon crawling role playing game with a modern execution but an oldschool heart. A group of four prisoners have shipwrecked on a secluded island filled with ancient crumbled ruins, mysterious shrines and a vast underground network of dungeons and mines.
