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 $208.2K — a different platform, not this one.

Quest Master

Quest Master is a dungeon maker inspired by the classics that made us love dungeon crawling. Use your imagination, alone or in local co-op, to make dungeons full of puzzles, traps and monsters. Upload them for others to explore and challenge yourself with others’ creations.
