Best game(s) for...

I guess racing games will benefit the most from using a controller. GRID, DiRT, NFS, etc.

You could also try out 3rd person games, like Assassin's Creed, Darksiders, Max Payne, and such. If you want.

Sonic Generations is good.

I'd either say fighting games like street fighter or some other bullshit even racing games. I perfer a mouse and keyboard for MMO's and any other kind of game.

As person below said, racing games are excellent for this, I recently acquired a 360 pad myself...The other game which it is amazing for of course, is twin-stick shooters, as it has..well...twin-sticks. Binding of Isaac, for example, even though this may take a bit more effort to get working, is an amazing game to play with it. Also, plane combat games, such as Wings of Prey are pretty damn neat.

Thanks for the replies. I never liked sonic games so generations is out for me. I totally forgot about it but I have Street Fighter IV so I'll try that too. I was never a fan of twin-stick shooters either but there are some fun ones. For plane combat games I'm always waiting for a good so if you suggest Wings of Prey I'll check it out and see for myself

Platformers: Super Meat Boy, Explodemon, Braid, and lots of other great indie games.

AAA titles vary. Action games are generally designed for controller use, but keyboard/mouse will be superior for shooters.

Try the Batman series! Or Just Cause 2. Or Grand Theft Auto.

it works well in skyrim i used it for my 1st play through

FIFA 12 , Need for speed the run

Zero Gear

Flying sims (including when you get into a plane/heli in Battlefield), Batman Arkham Asylum/City, Super Meat Boy, GTA IV

I don't want to play SMB right now I don't know why. I used a generic gamepad for my 2nd playthrough for Skyrim although I haven't finished that yet, because I'm stuck at the start of the Pilgrim's Path. Somtimes it sucks to be a mage. I have FIFA 12 but it's not that fun alone and getting my generic gamepad to work with it is a pain in the ass. If you know of any good games on NES, SNES, GBA or N64 you can suggest them too because I use emulators a lot and the 360 pad helps because with a generic gamepad it barely registers the analog sticks correctly (by that I mean that if I push it a little bit too much it thinks I'm pushing it all the way. Also is push the correct word to use? My native language is not English so I'm not sure.)

what about shank and shank 2?
also Rusty hearts is great with a Controller... well, is a bit messy, but once you get used to it, is awesome.

I forgot! I played through Batman Arkham City, so I doN't plan on playing Asylum right now. I played JC2 but I got bored of it. And I don't want to play GTA games now.

I saw the shank series but I don't really like it. I checked Rust hearts (even though the link doesn't work) but it didn't really appeal to me.

COD huehuehue

I forgot that Dark Souls is on PC (I didn't know the release date just that it's coming) I'll totally get that.

Shank 1&2 and Beat Hazard.

I don't really like arcade shooters. Also SORRY EVERYONE FOR BEING 'I DON'T REALLY LIKE THAT' 'I DON'T WANT TO PLAY IT'

I guess actiony slashy kind of games... but anything that's shooting (FPS or TPS) should be done with a mouse, like god intended!

Darksiders 1 and Darksiders II are great with the Xbox controller.

Magicka

Platformers are easier in general so super meat boy or sideway new york.

Burnout Paradise
Shank 2
Batman Arkham City

Batman Arkham City, Sleeping Dogs, Darksiders, GRID
playing each of those with Controller at the moment, and works perfectly!
