Honestly, quality 3rd person games are a bit hard to find... even for Windows, especially for OS X. I'm really not sure what else to suggest unless you were to go with Bootcamp.
ok ty for posts im not getting the new MBP in june(first mac) and i wanted to get some good games that i can order with the mac
and idk what steam really is. lol I've heard of it but never really checked it out could someone please explain ty
To clarify this statement, Valve is bringing their online game distribution system, called STEAM, to OS X. Valve is also natively porting all of their popular games (Left 4 Dead 1 + 2, HalfLife series, Team Fortress 2, Counterstrike Source, etc).
The Steam system also distribues a lot of a games that aren't made by Valve. These games are NOT currently being ported to OS X like Valve's games are. It's up to the developers of each individual game to decide if they want to get on board with that. So when Steam for Mac launches, the only games available will be Valve's.
