I just played KOTOR from the Mac App Store on my 13'' 2011 Air w/ i5. If you turn the graphic quality to the lowest setting, it runs very smoothly and has a great framerate. The fan will kick into high gear after a few minutes of play, but it settles down after a while. The thin notebook form factor results in you actually feeling the keyboard heat.
But what was most fascinating is that after about 2 hours of gameplay, I stopped playing and literally 5 minutes later the machine was a comfortable temperature and the fan was barely noticeable (but on, I think).
So, if you are hesitant on gaming on this machine, I can tell you that this one can handle some load. I wouldn't recommend playing anything heavier unless you don't mind cheap graphics. I think I will get SWTOR when it comes out because I'm a huge fan of BioWare games, but I don't expect to play it too hard core.
