I just bought a wireless gamepad, logitech 710. The only game I have for PC that is compatible with a gamepad is devil may cry 4. recommend me a game on PC that make good use of gamepad. I don't play FPS. I like rpgs and action adventure type of games. My favorite game is kingdom of amalur reckoning but i already have it on ps3.
Any of the Arkham games. Tomb Raider Dark Siders 1 and 2 Xcom Enemy Unknown Dark Souls 1 and 2
Basically any game that's a port of a console game and made in the past few years is better with a controller. Any game made with PC in mind will take advantage of the mouse and keyboard and wont work as well with a controller unless it's really simple and dual analogue setup doesn't hamper it.
