Because there are a lot of games that just released that have Wi-Fi and Wiki is unreliable in this area I'm starting this list to compile all the games that have online multiplayer that people actually own and are confirmed Wi-Fi.
Please post games that you own that have Online Multiplayer NOT just Wi-Fi features. (ie Metroid Prime 3 you can send people stuff but theres no multiplayer).
So far these are the titles that are 100% confirmed Wi-Fi titles that
I know of and have seen:
Battalion Wars 2
Pokémon Battle Revolution
Dragon Ball Z: Budokai Tenkaichi 3
Medal of Honor: Heroes 2 (No Friend Codes uses EA Nations)
Mario Strikers Charged
Guitar Hero III: Legends of Rock
I will update this list with every post that has a confirmed game with online multiplayer for wii. If game uses a none friend code system please specify so i can add that detail.
P.S. this would be a nice sticky if it gets going good
