Hi, I have the surface 2 and I was curious on how to go about playing console games like gta 5 on here with an Xbox controller, or if I could go on steam and play games off of there.
If you're willing to help over teamviewer that'd be great as well
You can play any game that is available through the Windows Store on the Surface 2, There isn't a STEAM Client in the Store so you would need an x86 Machine like the Surface Pro 2 as Krystal suggested.
Steam requires full Windows for the client install, so that means a Surface Pro 1/2. The Xbox controller support is for the Xbox-branded games in the app store only, AFAIK, not hooking up the console to the Surface like a TV (impossible).
I mean, you could theoretically use a remote desktop solution to play on another desktop, but I can't even imagine the horrible framerates when doing that.
