If you enjoy first person shooters and you don't have this game, you're missing out!
Using the WiiMote to aim and Nunchuk to move works perfecty. And you don't need to waste extra money on a Wii Zapper, which I found hard to control, but it's your choice.
When you're just starting to get used to the controls, you may get a little motion sickness, as the screen does react to almost any motion you make. But not to worry, you'll soon develop a steady aim and get rid of that motion sickness for good! What's even better, if you find it's too hard to reach a button, or you always seem to be pressing the wrong one, fear not. You can customize the controls by yourself!
The campaign mode will last you a good while, and you'll have a lot of fun playing it. The coarse language and blood may disturb you, as plenty of cuss words are thrown around. But you can turn these off in the settings.
You can even play with a friend in cooperative Squad Mate mode. But one thing I found kind of weird, you and your friend don't play two player split screen. Instead, your friend becomes something like a third arm. The main player controls the character movement and his/her pointer, while the second player controls his/her own pointer. The second player does not require a Nunchuk, just a WiiMote.
Although the graphics can't compare to other systems like PS3 and 360, for the Wii, they are pretty satisfying. And the cutscenes are unique and interesting to watch.
Now, I saved the best for the last. Online multiplayer mode! That's right, 8 player online multiplayer first person shooter action. There are different game modes including Team Deathmatch and Free For All. The competitive play and variety of guns, perks and maps will have you playing for hours!
Call of Duty: World at War is worth every penny. Do not hesitate to buy this game!
