No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $55.3K — a different platform, not this one.

Antihero

RUN A THIEVES' GUILD IN A GAS-LIT VICTORIAN CITY. Antihero is a fast turn-based strategy game with an (Oliver) Twist.
