I was playing the demo of this on my Windows machine yesterday, and really enjoy it. I'm considering buying it, but am trying to decide between the Mac or the Windows version (I wish manufacturers could just release one disc for all architectures, like Blizzard often does), but remember hearing horror stories about the OS X version being slow & crash prone.
Did these issues ever get resolved? I have a G4 Cube 500 & a Ti 500. Would the game be playable in OS X on these machines? They both have plenty of memory (1 Gig & 512 MB respectively). I don't have OS 9.X installed on either of them, so playing it in 9 isn't really an option.
