Well, I ended up buying a Wii because it had at least a dozen of good games, which is not nearly as much as my beloved PS3 but it's a good enough reason(s) to get one:
-Xenoblade Chronicles
-The Last Story (Will get it soon)
-Mario Kart
-Legend of Zelda: Twilight Princess
-Legend of Zelda: Skyward Sword
-Kirby's Return to Dreamland
-Wii Sports Resort (Yes, I actually enjoy this game)
-Donkey Kong Country Returns
-Metroid: Other M
-Metroid Prime 3: Corruption
-Resident Evil...something something Chronicles
-Mario Kart
-Mario Party 9
-Super Smash Bros Brawl
-Super Mario Bros. New.
-Super Mario Galaxy
-Super Mario Galaxy 2
-Tatsunoko vs. Capcom
-Rune Factory
-Sonic Colors
I think that's all I can remember right now. The main reason why I got a Wii was Skyward Sword, The Last Story and Xenoblade Chronicles. Two out of three down.
