50% of the people in the thread are going on about physics. Although noone has mentioned Havok, it might be worth posting a wish item: if no Mac port outright, at least use cross-platform technologies to allow the game to be ported more easily to other platforms such as Mac or Linux. So as things stand today, no DirectPlay, no GampeSpy, no Havok unless that situation turns around.

Whoever posts that message better have a thick skin though: somebody is bound to post a knee-jerk (emphasis on jerk) attack on Macs in response. :-)
