About the 360 games, the best racing games right now are on the 360 (forza and dirt) and PGR4, burnout, need for speed etc.
Sports, madden, nba, tiger, skate (amazing game), etc.
Ninja Gaiden, Huxley, Assassins Creed, etc.
You have to think that RPGs and JRPGs are coming by tons to the Xbox 360 it's not my favorite category but when I look at the list of games from the 360, OMG!!!!
I agree with you about the Wii, no games from 3rd parties, just 3 games from nintendo that I'm interested in and Night that I was really exited about is not looking very well. I'm one of those gamers that likes to play maybe 5 or 6 games at a time, so I need a really big library for that and for now the 360 is the only one who is able to offer that.
Right now I'm playing, Halo3, Bioshock, Skate, Forza, Madden, GRAW2 (best multiplayer ever) and Viva pinata. that is going to keep me busy for a couple of weeks when PGR4 comes out and I replacing Forza for that one, and then COD4 for bioshock, Tony Hawk for skate, Assassins Creed for Viva Pinata, Devil May Cry 4 for Halo 3 and so on. Lots of money to spend until the end of the year.
