Why don't you leave, troll? Isn't your time spent better doing something other than lurking on the MacBook Air section trying to tell us it is poor at gaming?
They will run it extremely playably on low to mid settings.
Extremely playable? What does that mean? And what do you base this on, soothsayer?
The real answer is it may be playable, and if it is it probably won't be unless it is on low settings. This based on the idea that it requires slightly more umph than Starcraft 2. No one knows for sure what the requirements will be, but this is the best estimate.
He isn't trolling. The MacBook Air with its HD3000 is going to struggle to play modern games and to say anything different is misleading. If it can play future games it will be at very low settings, at very low resolutions, and you will probably not experience the game in the way it was meant to be played by the developers. If that is fine with you, like it is with me, you can go bananas and win awards or eat a hat or whatever it is you do to express happiness. Stating that the MacBook Air will be "EXTREMELY" capable, whatever that means, of playing future games is like saying a toaster is capable of flight if you are able to throw it hard enough.
The final word on gaming is:
If it has came out in the last 5 years the Air can play it, and sometimes surprising well. If it is coming out in the next year, the Air will probably be able to play it, but at settings you probably wouldn't want to wish to view your girlfriend at alright?
