The discussion isn't whether someone bought a Mac for a specific purpose or not. The discussion is about the fact that players bought a specific port of a game and had an expectation that it would work. Personally, I'm in your camp in very *general* terms; I game on PC and have been a PC fangirl since DOS. For gaming, it's the best platform.

That does not in any way invalidate the facts of the case. These folks bought a license for the game with an expectation that it would work on the system it was advertised for, and that is the scope of the discussion. Period.
