Both play and run great on this machine (2.4 / 8GB). Resolution is at 1200x800 and it runs very fast, but even when you bump it up, it is still more than playable. The fans turn on, but they are quieter than on my old 13" Air, and they power down about 15-20 seconds after quitting the games. Very impressed. Not top performance by any means, but you can at least dabble with some decent games. I couldn't even load Civ5 on my Air, much less play it.
