Do any 3rd party games currently have online multiplayer? I can't think of a single one. The only games I can think of that have online are SSBB, Mario Kart Wii and Mario Strikers. Is the lack of 3rd party online becasue Nintendo won't provide the servers for it or becasue the 3rd parties don't care enough to make an online mode?

 Ea has medal of honor heroes 2 online with thier own servers( no friend codes).

Here is a list of all wifi enabled games. http://en.wikipedia.org/wiki/List_of_Wii_Wi-Fi_Connection_games

Edit; Surprisingly the only people trying is EA. 

Yeah, EA games have a pretty good setup. Others will follow. This one area that I think Nintendo sucks at.

Actually two of the top three online Wii games are third party. Pro Evolution Soccer 2008 has smooth online, and has provided me with hours of fun. Previous to PES2008, MOH:Heroes 2 WAS the best online game on the Wii, currently it's MKWii.

MOH has 32 player online, no lag, and works very well. It also has the best FPS controls of any non PC game on the market. (Yes, even better than Metroid Prime 3).

 Too bad the single player is pretty mediocre. It would have been one of my favorite wii games if it wasn't.

from what i own, these have online:

Dragonball Z B T 3 (not always working)
Nights
PES 2008
Mario and Sonic

I haven't tried it online, but Guitar Hero III was doing crazy numbers on the WFC charts. I haven't read anything bad about the online, so I'm guessing it works fine.

Madden 08 has online multi-player, but I gave up on it months ago. Half the time you do a quick match-up the connection fails. For some reason you can't connect to certain people. Me and my brother tried every way possible to connect for hours on quite a few different nights with no success. Then there is lag in about half the games that do actually get going online. Pathetic. Hopefully 09 will have this corrected.

ya MOH2 is pretty solid for online. Im kinda pissed about no local multiplayer via split screen or co-op.

GH3 is ok, sometimes its hard to find someone to play against. It might just be because Im a night owl.

I don't own anything else so far that's online for the Wii
