Throw down your ideas here.
1. Ghostbusters.
C'mon, the Wiimote is perfect for this kind of thing. Just think how awesome it would be to lay waste to expensive buildings while waving the controller around like a maniac.
Oh man, I don't think I ever thought about a Ghost Busters game for the Wii, that would be awesome!
2. Virtua Cop Collection
We need more light-gun style games for the Wii, and a VC collection would be great, maybe bundled with a brand new VC game.
Good suggestion, I'm hoping for more light-gun style games for the Wii as well, these ones would be great, as would Terminator 2.
3. Star Wars.
Lightsabers. 'Nuff said.
Of course

.
Here are my ideas:
1. ) Rez - The Wii had've to been designed for this game, just play Rez to see what I mean. The control is absolutely perfect for it. Also a Panzer Dragoon game as GUTS mentioned would be cool, but Rez moreso with the targeting thing.
2. ) Any baseball game (a new Baseball Stars would be great) - Not saying that Baseball on Wii Sports wasn't good, because it is a lot of fun and shows off the potential for a Wii baseball game, but a new baseball game completely designed for the Wii would be great. For fielding, I think it would be nice if you use the d-pad on the Wiimote to move and to throw to a base, you hold down the B-trigger and then press the direction according to the base, or on second thought, holding down B and actually throwing the ball in right direction.
3. ) Laser Tag -

4. ) Ys - New or remake.
5. ) Shining Force - A new Shining Force would be great, especially since you could just point-and-click to where your troops go in battle.
