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 $13.7M — a different platform, not this one.

Papers, Please

Congratulations. The October labor lottery is complete. Your name was pulled. For immediate placement, report to the The Ministry of Admission at Grestin Border Checkpoint.

Decide the fate of countless hopeful immigrants while balancing your income and family needs.
