My favourite of the moment is Test Drive Unlimited, seeing as I already have the USB steering wheel with the gear change paddles on then it was the obvious choice for me. Where else can you by a $500,000 Ferrari Spyder and drive it at full speed on the public roads of Hawaii? Then when you accumulate lots of money you get to buy big property like mansions!!

I am into zelda on the wii at the moment loving it but it is frustrating!!!

I've not long completed Zelda, you'll love the end battle. A game that is actually a lot better but still not as well-known is a game called Beyond Good and Evil. It's a masterpiece, check it out!

Oh, so many, this could be a long post lol.
