Holy, I hope you're joking... wii? Seriously?
You're fucking right I'm serious.
These are some of the games that I love for the system, the kind of stuff that's actually fun—and not all about running down ugly monochromatic corridors accompanied by piss-poor, repeated, backward-thinking gameplay:
No More Heroes
No More Heroes 2: Desperate Struggle
Super Mario Galaxy
Super Mario Galaxy 2
Zack & Wiki: Quest for Barbaros' Treasure
Silent Hill: Shattered Memories (better on Wii than PS2 'cos of motion controls and slightly better graphics and effects)
The Legend of Zelda: Twilight Princess (though I prefer this on GameCube despite its lack of 16:9)
Mario Kart Wii
Wario Land: Shake It!
New Super Mario Bros. Wii
MadWorld
Muramasa: The Demon Blade
Super Smash Bros. Brawl
Teenage Mutant Ninja Turtles: Smash-Up
Resident Evil 4 (the best version of the game available)
A Boy and His Blob
Elebits
The House of the Dead 2 & 3 Return
The House of the Dead: Overkill
Resident Evil: The Umbrella Chronicles
WarioWare: Smooth Moves
Rayman: Raving Rabbids
Excite Truck
Resident Evil Archives: Resident Evil (better than the GameCube one since this one's progressive scan)
Resident Evil Archives: Resident Evil Zero (same as above; progressive scan makes a huge difference, especially on an HDTV)
Boom Blox
And I still have to get
Sin & Punishment: Star Successor. Then there's some other games I own but haven't gotten around to playing yet that I'm sure kick ass, such as
de Blob,
Let's Tap,
Dewy's Adventure,
Nights: Journey of Dreams,
Little King's Story, and
Metroid Prime Trilogy (though I hear the first two games are missing some effects present in the GameCube versions, which sucks, but adds widescreen support and supposedly some new textures and effects).
There's also some great-looking games coming out:
Metroid: Other M
The Legend of Zelda: Skyward Sword
Kirby's Epic Yarn
Donkey Kong Country Returns
GoldenEye 007 (on the N64, one of the last great first-person shooters, in my opinion—I can't stand the FPS genre now besides something rare and unique like
BioShock; the whole genre has plateaued)
There's also some really great WiiWare games:
Castlevania: The Adventure ReBirth
Contra ReBirth
Zombie Panic in Wonderland
Mega Man 9 (according to critics it's best on Wii)
Mega Man 10 (not sure if this one is, though)
Muscle March
—and probably others I'm forgetting
Add all that to the great backlog of amazing old school games, including previously-unreleased-in-North-America games like
Sin and Punishment (now, like all the other Virtual Console N64 games, in full 480p resolution, so it looks and operates way better than on its native console, barring lack of ideal N64 controller; Nintendo oughta release an N64 Classic Controller) and
DoReMi Fantasy, and you've got one kick-ass little console.
So yeah, I'm serious. For my tastes, Wii wins this console generation hands-down. Couple that with the amazing library the DS has, and the ever-rockin' DSi XL, and I'm one happy Nintendo fan.
The games I've enjoyed on the PS3 and 360 are few, and most of the ones I do like are PSN and XBLA games (mostly ports). Though the 360 has
Deadly Premonition, one of my favorite games in recent memory, and I thoroughly enjoyed
Silent Hill: Homecoming and
Heavy Rain on the PS3 (and am looking forward to playing
Siren: Blood Curse). Currently playing
3D Dot Game Heroes, which also rules.
