Buying a Wii this week (Sony fan)

[Mnementh]

If you like RPGs: don't miss Xenoblade.
If you like Action Adventures: nothing can go wrong with Zelda (both of them).
Pikmin new Play Control is a great strategy-game.

You should get WiiSport and WiiSportResort, they are pretty good games. Don't bother with WiiPlay though.
