Yes, it is well worth it if you like First Person Shooters. The controls are the best of any Wii game. check out this link: http://wii.ign.com/articles/833/833766p1.html that is the IGN review....nuff said.....
yes for sure if you have online. like cantgetawii said the story line lacks. the visuals are alright. but i have to disagree and say that even though metroid was the better game, moh had better controls. their basic engine of pointing and shooting is the same but in moh you reload shotguns with the nunchuck. twist the wiimote to zoom in with snipers and stuff like that. but still both games excels in controls.
Definitely, I'm addicted to it right now. Its a great game, the online is great. I really only bought it for the online, and I'm not disappointed with it. I would highly recommend this game for all wii users.
It is not worth it!!! Especially after playing other online games on other consoles. Yeah, the controls are some of the best (I agree with CantGetAWii that they are not better than Metroid's controls) but the online is just mediocre and has a lot of bugs. If you have never in you're life played a FPS online, you might be impressed.... maybe.... or if you've never played another WW2 game...
