The shit hits the multiconsole fan....

[A Black Falcon]

Yeah, it was originally going to be multiplayer-focused... but then on X-Box they couldn't do that, so maybe the single player game was rushed some... but still it was very well done. I don't think I'd call it a direct Mac port... the game changed too much over time to say that... but a decendant of that original Mac game? Yes... still, I very much doubt that Halo will be coming out on other systems... though the possibility of Bungie somehow managing to get out the Halo engine for other developers to use on other platforms is interesting... if unlikely-sounding.
