If you love FPS and own a Wii then I recommend this game. But the fun doesn't last long.
A moving campaign mode which has a range of difficulties.
In-game characters such as Sgt. Reznov can be entertaining.
Multi-player has something different in store every time with different game modes, killing new people and completing prestiges.
Wide range of weapons.
The not so good side:
The famous Nazi zombie mode is not included in the Wii version.
Many other things that are in the 360, PS3 and PC aren't included (eg. other multi-player maps and vehicles in on-line play)
Not many on-line game modes.
I do not think the Wii has been put to it's full potential graphically
The campaign is over in a matter of hours
Infinity Ward do not patch up the glitches that people tend to use on-line which gets pretty annoying.
Sorry, I didn't have much time for this review.
