The reviewers have been hard on this game. It has it's faults, but I think it is the best FPS out at it's release.
Gameplay:
The campaign is very good although pretty short. you could probably sit down and beat the campaign within a day if you played diligently.
The multi-player is quite good, but I recommend you try to find a big screen to play on if you do more than two player or else you will be doomed when aiming.
The game is a bit on the easy side although it can be challenging especially near the end of the game. The AI isn't astounding like in Resident Evil 4, but i's not completely stupid like in Call of Duty 3. The AI doesn't really do much but what it does it does pretty well. You won't see much collective strategy from the AI though.
Controls:
I couldn't ask for much more. The game blends the targeting and moving functions together much better than previously released games. The controls work well and I am much more proficient at shooting with the Wii remote than with a standard controller. The only gripe I had with the controls was the about-face command using motion controls on the nun-chuck. It often misread reloading or standing up motion as an about-face so I turned it off in the options.
Graphics:
The graphics aren't the world's greatest but they aren't horrible. Most of the graphics are pretty good except for the vegetation. The grass is pretty baldy rendered, but I'm sure they were trying to save the frame rate. The rest of the graphics are pretty good. My biggest problem with the game is that they made the graphics a little too realistic in some situations. Inside some of the buildings can be so dark you just have to look for muzzle flashes and fire. Aiming the through the "real" sight in dark areas can be practically impossible. The same thing happens occasionally outside as well. This is great for realism but can be a little annoying. Besides this the world is very well rendered. All the buildings look very realistic and nothing really looks out of place.
Sound:
Not much to be said here except that the sound is top notch. They did a great job with not only the background sounds as well as the effect sounds. It is really great to hear your equipment rustling around when you sprint to cover, or hear the boards slowly creak as you walk through the war-torn buildings. All the voices fit very well and your allies can be very helpful with their warnings.
