One thing about the fall is that there is a whole glut of games that come out just in time for Christmas and other various winter holidays. The games that I are really looking forward to in late 2005 and early 2006 are.
PS2
Soul Calibur 3
Nintendo DS
Mario Kart DS
Animal Crossing DS
Sonic Rush DS
PSP
SSX On Tour
Grand Theft Auto: Liberty City Stories
Star Wars Battlefront II
Ghost In The Shell: Stand Alone Complex
Harry Potter Goblet of Fire
Ys: The Ark of Napishtim
WWE: Smackdown vs Raw 2006
Viewtiful Joe Red Hot Rumble
Xbox
Tony Hawk's American Wasteland

Viewtiful Joe is listed under your PSP category, but not the DS one?
You should look into that, its pretty bitching/spanky/hot or whatever those damndest kids say these days.
Animal Crossing Tony Hawk and Mario Kart for the DS are on my list.
