only driving game thats interested me is the burnout series, i have burnout paradise which is good for a bit of pick up and play from time to time. I do have Kameo here too, that came with the xbox which i've played for a bit, again its quite good for short periods of distraction.
However i really am one for getting immersed in a game and its storyline, to give you an example the games I have played to completion over the years are the likes of the final fantasy series, fable, neverwinter nights, oblivion, ultima series etc. So i'm really on the hunt for something RPG based. So far as i understand it Mass Effect is the pinnacle of that on the 360 currently so not sure if i will find anything to compare, until Fable 2 is released of course
