I know you said that you didn't write it, but I've just gone through and made some comments on the list. You can't just copy-paste a list of 'exclusive' games and expect people to think that the system is great. Even of the games that are exclusive, not all of them are worth getting.
1080: Whitestorm - looks good
Acceleration - a game most people haven't heard of and probably don't care about. This is the developers second game ever, so don't expect anything great. They have published games before, and not just for GC, so I'm not sure how exclusive the game will stay
Animal Crossing - looks good
Backyard Football - not exclusive. Being developed by left field, but they are no longer second party
Beach Spikers - look ok, so far
Bloody Roar: Primal Fury (released) - this particular game might be exclusive, but the series sure isn't
Bomberman Generation (released) - same as above
Camelot RPG - not enough info to comment
Darkened Skye - is on pc
Diehard Vendetta - probably crap
Dinotopia - probably crap
Disney All-Star Basketball - dont think i need to comment
Disney All-Star Football - ditto
Disney All-Star Skateboarding -ditto
Disney All-Star Soccer -ditto

Disney's Magical Park - ditto (even though ive never heard of this one)
Donkey Kong Plus - this is a gba game
Donkey Kong Racing - might not ever be made with the rumours surrounding rare
Dora The Explorer - = doshin the giant? because otherwise ive never heard of it. but if it is doshin then should be good

Godzilla: Destroy All Monsters Melee - sounds pretty average
Home Run King (released) - crap
