I’m fascinated by attempts to remove violence from first-person shooters. One Wolfenstein 3D mod replaces enemies with giant coloured marbles and turns hanging skeletons to hanging pot plants, yet leaves in all the Nazi symbolism “in order to keep the original ‘spirit’ of the game.” That is, I think, a serious attempt at de-violenceing. More jokey is Happy Doom, where “you are a little boy who has a basket of flowers” and give them to “cloud people” to make them happy and sleep.
Super 3D Noah’s Ark, a game I never knew existed, was wholly serious. It’s essentially Wolfenstein 3D, and built on the Wolf3D engine, but with Noah running around the Ark, ‘feeding escaped animals’ using high-powered catapults. And now it’s been re-released.
