No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $6.7M — a different platform, not this one.

Surgeon Simulator

Malpractice makes perfect. The most critically acclaimed, one-handed, clumsy, bumbling, surgery simulation game has now arrived on PS4™! Players use their controllers to operate one of Doctor Nigel Burke’s flailing arms, in an attempt to perform life-saving surgery on his peaceful and trusting patient, Bob. Includes the exclusive PS4™ multiplayer offline co-op mode. Two controllers, two hands . . . still one poor Bob! Nigel’s surgical adventures will take him through over 20 operations and across 6 different locations, including brand new Eye and Teeth operations. We’ve also added over 50 trophies for you to collect and admire. Fantastic! Eurogamer - “It's a bloody riot.” Joystiq - 'four out of the five doctors we didn't actually ask said being awarded a platinum trophy in the game is not equivalent to earning an MD”
