I know there is some xbox 360 emulators existing, so if i get skate 3 on it i can play with the xbox controller that could be awesome!
But what i wana ask you right now is do you think it's possible to enter the game's folders and maybe change some things in the game like objects limit on CAP, etc... And maybe it could be easy to share skateparks...
