i love the Wii the graphics aren't that bad considering Nintendo decided to focus on controls more than the graphics. i love the graphics for LoZTP, Prime 3, SSBB, Mario Galaxy, Fire Emblem, No More Heroes, and a few others. Can't wait till they put the first two Prime games on the Wii.
The Wii does have awesome single player games, it isn't just a party console.
Some other games worth mentioning:
Resident Evil 4. (Best version of the game, and better than the crappy game that is 5)
House of the Dead: Overkill
Guitar Hero World Tour/Rock Band (take your pick, I'm a GH person)
Another Code R
Disaster Day of Crisis
House of the Dead 2+3
Resident Evil: Umbrella Chronicles
Trauma Centre Second Opinion and New Blood
Zak and Wiki
Mario Galaxy 2 (Upcoming)
Resident Evil: Darkside Chronicles (Upcoming)
Red Steel 2 (Upcoming)
Muramasa: The Demon Blade (Upcoming)
No More Heroes 2 (Upcoming)
Cursed Mountain (Upcoming)
Sin & Punishment 2 (Upcoming)
Metroid Other M (Upcoming)
Zelda (Working Title, Upcoming)
Just because I have the impression that most in this thread aren't aware of all the good games on the Wii. If you want an opinion on any of them, just ask.
EDIT: I'd love to see someone top 28 good games on the PS3. XD
