Noob with a Xbox Controller...

Castle Crashers LOL

If you like the keyboard and mouse, then that's fine. Stick with whichever works best for you.

Sleeping dogs works really well with a controller, you can go through the whole game without the need for your mouse and keyboard. Some games like Dark Souls and GTA4 are nigh unplayable without a controller, but I'm not sure those are good "training" per se. Wait for some better responses. lol

Super Meat Boy

GTA, that's also how i got my driver license.

Do you have a platformer or a dual-stick shooter? These are probably the best to train. GTA-like games are also good.

Fable 3.

Braid, Flatout, Street Fighter.

A more comfortable chair?

Darksiders, Renegade Ops

Dark souls although it may cause you to violently throw your controller to the ground. Other than that, castle crashers, Ys origins and oath in felghana, bastion, any good platformer like braid and such.

I know what you mean; I just take a break from playing FPS/RTS etc and play a platformer/driving game and play that with the controller, makes a lot more sense than getting frustrated playing a game with substandard controls.

I would suggest Borderlands 1 / 2. Both work well with a gamepad. I'll also agree with the Ys games, though be sure to customize the controls since clicking the right stick for the menu is weird.

But SR3 is the best with a controller!

I recommend playing Shank series and if you like MMO, DC Universe is better with xbox controller

Dark Souls, it 10000000000000000000% needs a controller.

Not to mention, it's a great game in general ^_^

I guess everyone has their own preferences, but I get frustrated using controller for FPS. The mouse just seems to much faster to aim with. I'm not sure if this would disappear over time.
I like using controllers for games like Batman, Super Meat Boy, and Saints Row. Been using it a lot for Hotline Miami and Binding of Isaac in the last few days, not completely comfortable with dual analogue sticks for moving and aiming yet though.

Both those games would be harder with a controller if you ask me, actually I never use a controller in any game that has me aiming.

Driver San Francisco, Assassin's Creed, Batman Arkham Asylum/City :)

Just a suggestion, do not play FPS games with a controller.

GTA, AC, and sports games mostly e.g. 2k13 and fifa

Some people have already suggested Dark Souls, which I support. But I'll also throw Hoard out there. It's a pretty damn good game, even if it's a bit on the obscure side. It handles so much better with a controller than with a mouse and keyboard, too, which I didn't expect.

People are suggesting Super Meat Boy, which personally, I think is a horrible idea. It's a great game, but if you're going to be learning to use a controller, you might not want to start with one of the most mechanically difficult games ever created.

Dungeon Defenders :P

Mark of the Ninja is great, I wouldn't play Magicka without a controller, Max Payne 3 is good, Spec Ops, Mirror's Edge...

Just don't play Hotline Miami with a controller. SO ANNOYINGLY ADD.

GTA or portal because it will help u aim i guess
