I'm looking for a good video game for my Nintendo Wii, anyone know a good one?

You could try any of the Call of Duty games (3, World at War & Modern Warfare)

The only other game that springs to mind is Battalion Wars 2

Call of duty series are all pretty good, though the later ones tend to be shorter in game play (Modern warefare).

Cod4Mw:R Is Great! Also I got "The Conduit" It's a bit like call of duty its just bad because you can't pick what gun you will use when your Playing Online.

Call of duty black ops I heard it just came out for wii

In my opinion the Conduit is THE best Shooter game Exclusively for the Nintendo Wii, and plus The Conduit 2 is going to be coming out soon enough
