Will you guys suggest me a good game? Im looking for any platformer, adventure you guys think is fun, preferably one i can play using a xbox 360 controller

Suuuuuuuuuuuuuuuupeeeeeeeeerrrrrrrrrr Meeeeeeeeeeeaaaaaaaattttttttttt Booooooooooyyyyyyyyyyyyyyy. ^_^

For 2d platformers, there's also Rayman Origins, though I'm not 100% sure whether you can play the PC version with a 360 controller. Since it's also available on the 360, I'd guess that you probably can.

And well, there's the other Rayman games available here on GOG too. Bit iffy regarding controller support though.

You can, I played the demo with X360 Controller.

You tried Spelunky? I don't know if you can play it with xbox controller, but it's a lot of fun.

'specially since it's in the current Humble Bundle.

Though it is possible that some of these don't have Xbox 360 controller support, here are some good ones:
Trine
Braid
Frogatto & Friends (free)
Capsized
Cave Story (free, though there is an enhanced version that costs money)
Limbo
Sonic CD
Psychonauts
Eternal Daughter (free)
Escape from the Underworld (free)
Spelunky (free)

No idea whether it will work with xbox 360 controller, but how about Beyond Good and Evil? It's on GOG.
