Minecraft wiki entry for 0x10c, associated text: On April Fools' Day 2012, instead of a typical Minecraft April Fools joke, as was the case the prior year and every year since, Mojang launched a satirical website for a space game entitled Mars Effect,[8] citing a lawsuit with Bethesda regarding the title of the Mojang game Scrolls as an inspiration.[9] However, the gameplay elements remained true, and on April 4, 2012, Mojang revealed it as an actual space sandbox title, 0x10c.[10]
