Well . . . it depends on what you mean by Game, these games are now considered "Casual Games", similar to angry birds. But more complex games like lets say "The Elder Scrolls Skyrim" is not upto par with that. For example, watch a video of it here:Skyrim Unedited Gameplay
this was a recent video of the game, which I can say its amazing.
Anyway, Mac is ok, but as long as its not recognized by the software and gaming community, its still not worth it, of course depends on the person. Im an IT guy, so I avoid Apple products like the Plague, but mostly for technical and performance reasons rather than just hating it and all.
Dyson (or Eufloria) is one of those games that is in the ally of Mac games, its how mac essentially introduces himself, hence why I support the movement towards making a playable version on mac.
