+1 Xenoblade Chronicles. What can I say? I normally hate RPG's that aren't fallout. But not only did I kept playing xenoblade, I actually bought it. I don't know much about JRPG's, but this is just a good game in just about every way I can think of. And that's mostly the little details (fast loading screens, intuitivity, lots of sidequests, compelling world, a battle system that actually has some action, and so on).
...and with all the hype, it surprises me I'm the first one to mention this game here.
+1 wii play: motion. Now just a second...considering you should subtract the price of the wiimote plus, you should actually ask yourself if you want to pay a little extra for this game. And IMO: yes. Sure, it has a few "average" or even "meh" games, but teeter targets is freakingly addictive, and some other games (wind runner and that whack-a-mole game, to name a few) are pretty decent & fun.
+1 De blob 2: okay, it gets a bit repetitive after a while, and aside from the theme, it won't win innovative prizes. But it's a fun little 3D platformer with hilarious cutscènes.
+1 Mario sports mix: granted, I just play volleyball with this game (being Bowser surrounded by swimsuit ladies is all you really need
). Not for the die-hard gamers, but ey...for a wii game, it more than qualifies.
(I almost feel like I should vote for conduit 2 as well here. Haven't played beyond the initial stages, but looked damn impressive from what it showed).
