I should be able to make it. As far as rhythm games go, while I'm not sure I'm down for Guitar Hero or DDR (I think I'm done with those games for good), I am looking forward to Frequency, Amplitude, Samba De Amigo, Vib Ribbon, Space Channel 5 1 & 2, Every Extend Extra, etc. And don't forget the non-rhythm music games such as Rez, Chime, and Lumines. I hope we get to play these games not listed in the OP.

Nick, do you need me to bring any games? I have most of the games I listed above.

Hey Bob, we better not be playing the US version of Beatmania. I will riot if we do.

I'm also looking for the following 360 games:
Assassin's Creed (Not PH)
Culdcept Saga
Family Game Night
Mass Effect (Not PH)
