The game halo was original developed for PC. Then They took a long time to develop it and ran out of money. Then your freind and mine decided to make a console system. Of course you would need a great game to debut your new console so M$ bought out Bungie. I thought i heard rumblings of a PC ver of halo. At least that is what they were saying at the release party. about a year ago.

side note. I thought it very amusing when i went to the Halo release party. They used mac laptops to run demo movies.
