Minecraft is digging its own grave with its latest release on XBLA -- and by "grave" we mean "lavish, gold-plated throne room with indoor pool and grape-feeding robots." Minecraft was profitable within an hour of its launch on XBLA, developer Markus "Notch" Persson tweeted today. That's on top of Notch's multi-million-dollar PC version. Based on leaderboard participation numbers, Minecraft sold more than 400,000 copies in 24 hours, Notch said. Minecraft broke digital sales records for the console, selling more than any other XBLA title in its first day, according to Microsoft. Earlier today, Notch tweeted that he had sales numbers for Minecraft (turns out they were the above leaderboard figures), which sparked a conversation about the inner workings of XBLA developer contracts with Fez's Polytron. Polytron still doesn't know Fez's exact numbers, even though it came out a month ago. "Standard procedure" according to Polytron is "you find out how much you sold when you get your first check three-four months later." Notch thought getting immediate numbers was standard, but he avoided contract negotiation and doesn't know what it says on the subject, he replied. Minecraft also gets free updates, "which is something every other developer on the platform is told is simply not an option," Polytron wrote. Notch replied: "We had to fight for that, and we got a limited number of them. Not sure why they don't like it."
