An article on PC Gamer talks with Mojang's Markus 'Notch' Persson and Tobias Möllstam about 0x10c, their upcoming space simulation. "The goal is to have it feel a bit like Firefly," says Notch. "You can try to land on a planet but you mess up and, instead of having the ship just explode like it would in real life, the landing gear gets broken. Then you have to try to fix that by finding resources. Instead of the adventure being flying from here to here, it’s: I set the destination, oh god I hit a small asteroid and the cloaking device broke. I think they really nailed that kind of emergent aspect in FTL." They also include a link to this trailer showing footage of a "first draft" of an "art test" for the game.
Slashman wrote on Oct 13, 2012, 10:33: Minecraft sold over 9.2 million according to sales figure from Notch. I think he could afford to do something slightly more than what we're seeing in that video.
Notch can afford to do anything he wants to, and he wants to design and program a game by himself or with a very small team. It's not like all of Mojang is working on the game.
