Best-selling videogame conceived at a game jam event

Surgeon Simulator 2013, which was first conceived as a prototype at the 48-hour 2013 Global Game Jam, has been downloaded 3,009,771 times according to its UK publisher/developer Bossa Studios. The sales figures were across all platforms the game had been released on and were correct as of 17 March 2016.

A game jam is an event at which teams of developers are tasked with making a game based on a theme within a designated time period, commonly 48–72 hours. Surgeon Simulator 2013 was a blackly comic simulator that pitted players into the shaky hands of budding surgeon Nigel Burke. It was often likened to the nostalgic tabletop game Operation. In a positive 7/10 review, PCGamesN described it as "hilarious to watch and ridiculous to play" and "stupidly fun in a way that makes writing about it feel utterly futile".
