I've got one. Mario Kart is... y'know, fun? Especially online. No More Heroes is... y'know, weird, but kinda fun?
Okami, Canis Canem edit and Resident Evil 4 are all... y'know, PS2 games.
Mario Galaxy is yet to be unwrapped and played so provides a glimmer of long term hope, but once again, Nintendo have suckered me into buying a machine for their 'innovation' and merely released a bunch of additions to their ongoing gaming series (Mario / Kart / Zelda / Metroid / etc) that dribble out at the rate of one a year.
I want to play the new Prince of Persia game, so maybe I'll trade it in now and save up some pennies for one of those Xbox Station 3 thingys...
