I purchased a moga game controller for my s3. It turns your smartphone into a psp. link: http://www.amazon.com/MOGA-Mobile-Gaming-System-Android/dp/B0096L2SJ0/ref=sr_1_1_ha?ie=UTF8&qid=1368038908&sr=8-1&keywords=moga Natively it supports a decent amount of games. Big games like Dead Trigger, Shadowgate deadzone, etc. The beauty of this is there is a driver on the marketplace that allows you to control your emulated games using this beauty. If you like to play old school games and don't prefer touch controls, then I highly recommend this device.
