This is a great history of Bungie, the Mac game developer that brought us Marathon (and eventually published, in a sad turnaround, Halo for Xbox). I wasn’t familiar with the story of Bungie trying to sell itself to Apple after getting an offer from Microsoft. It’s hard to imagine a sale to Apple turning things around for the Mac as a gaming company, but it was the killer app for Xbox. In any event, I spent a lot of time playing Marathons 1 through 3 in college and thereafter.
