Guild Wars works on a Mac now, with some flaws:
The typical dock/menubarproblem where full screen doesn't quite work.
I also get no sound at all, and the heads of the models are bugged. Mostly the har is gone, and on i.e. the Warrior with Knights helmet, has no neck.
I'm not sure what causes this. The "helmets", perhaps? (despite i.e. Knights helm working).
If sound could get working, that would be great.
Oher than that, the game registers DirectX, and thus uses DirextX8 graphic, which is all right. Game's playable in my eyes, if you don't care much for sound.
