Why is Blizzard the only mainstream game developer that develops simultaneously for the Mac and PC? But not only that, they release both versions in the same box, at the same time, and with great support from the start to the end of the games life- I haven't really found anything that explains this so I'm curious as to why they seem to be flying their own ship on this, and why other software companies have not followed suit. I assume that if it were not profitable, they would not do it, so what gives with the others? And I do not mean the crappy games, I'm talking things like UT 2004, Quake series, SIM series, etc. Games that you know are going to sell well to both PC and MAC.
