Man, I hate my Wii as I'm a big fan of first person shooters, which are non-existent on Wii. I should be getting Mario Kart in a while though, which should be good...
The Wii's my favorite next gen. system by far. Between Mario Kart Wii and Super Smash Brothers Brawl (which I am a master at... I'm not lying, if you wanna fight me just message me) I'm totally set and totally happy right now.
I love how the Wii has brought forth motion sensing technology into home gaming. I look forward to seeing what more advanced systems Nintendo will come up with. My favorite game is The Legend Of Zelda: Twilight Princess.
