100,000 is increddible for an xbox live arcade game, especially for six weeks. I don't know exactly how much the take is for Microsoft, but for Indie games they take 30% of all sales with a sales minimum for a payout. I'd have to imagine the arcade games are nearly the same payment structure. If that's true, and this guy developed the game by himself, he just made over 700,000 dollars in a month and a half ... even if it took five years to develop that averages out to alot more money than I, or anybody else commenting here makes. I haven't even heard of this game until now ... and I think I'll download the trial.
