...so um I'm reviving this thread. I take full responsibility for whatever shitstorm may follow.
May have been brought up already (though I can't find it with a search), but Steam's coming to Mac. Not only that, but Valve's porting its back catalog over, and releasing all its future games for both platforms. Not only THAT, but if you bought the game for Windows, you can download it for Mac at no additional charge. Not only THAT, but if you're playing on your MacBook Pro and then go home and play on your Windows desktop, your save will go straight across.
First of all, this could be a major step in bringing the Mac out of the ghetto as a gaming platform. Valve's joined Blizzard in showing serious love for Mac users, and could lead other devs to do the same.
And second, all that shit about getting the game on multiple platforms? Most companies don't do that. Blizzard does, but I can't think of another major publisher off the top of my head. (I remember a friend who owned both platforms bought KotOR for Mac some years back and discovering he'd paid twice what the PC version had been discounted to.)
Anyway, stuff like being able to seamlessly transfer games across platforms is a serious value-add in my book. And it makes for an interesting tradeoff for what you get with an oldschool disc-style you-can-resell-it-but-it-won't-work-on-a-Mac (again, Blizzard notwithstanding) game purchase.
I am guessing TA is still not interested, but I find the whole thing pretty impressive, if still imperfect.
