1. Need for Speed: Most Wanted (2005, 360) the best of the nfs games by far, as well as the original most wanted. My first "next gen" hd game. Such a wonderful racing gem.
2. Burnout Paradise (2008, ps3) great racing game, seamless drop in and out online, replayability like crazy, guns N Roses theme song
3. Mario Kart 64: best Mario kart for me. Had a blast playing this game. Much memories.
4. Crazy Taxi: one of the only games I remember playing with my sister. Fun as hell.
That's about all I can list. I've played the gran turismos/forza/ect. But personally I think none of them are fun at all. Boring games.
