I currently have mario kart wii, call of duty:waw, super smash bros brawl, guitar hero WT online games.

So i order according to my fav online game (but all are good):
1. mario kart wii - must have! don't stay home without it. even if arcade racing is not your genre you should get it. i bought this for my daugther, and was not into arcade racing. But now i play it as often as her, and usually play online, even if i play with her.
2. call of duty: waw - depends if shooter is your genre. If it is don't stay home without it.
3. guitar hero WT/Rock band 2 - the offline will keep you very busy already. But i do play online once in a while when i need 'company'.
4. super smash bros braw - Bought this for my daughter, so i normally play with her and not online. For online is hard to get people to play with unanonymous users. I dono, for the times i have tried playing online, i can't find anybody to play with.

Hope this helps

I have both guitar hero WT and COD 5 (WAW).
Guitar hero is kick ass game! i play this the most.
COD5 online is good. No lag, up to 8 people simultaneous. but can't use wii speak. and yes, the game can use Wii zapper (i don't have the zapper, but it states that in the opening screen). i think FPS on wii is more intuitive and real, coz is closest to the real thing. You really point the 'gun' and 'shoot'. Unlike the PC where u need to mash keyboard keys to move. Even worst for PS3/xbox360 coz aiming is hard using the analog stick.

Guitar hero metallica i heard the Wii version don't have DLC (they may change, but for now no DLC). But they will include extra songs which won't be available in 360/PS3. Think that is stupid lah. How can no DLC.
