which is the better online fps for wii medal of honor herpes 2 or call of duty waw?

I would say WaW but I have never played MoH. I heard that MoH doesn't have that many varied weapons as WaW though.

WaW by a mile. The Conduit will soon take that title, however.
And if we're lucky MW2 will take it from TCon.

This is based on what I've seen said on this forum but MoH: H2 has better controls and more people available per game but WaW has more content and better graphics. I can't really say for myself.

WaW because it is the only FPS shooter online in AUS. Lame EA took out multipplayer from MOH here. So everyone returned it as quick as we baught it.

It's tough to say. I have both MoH2, and WaW. As was previously said, MoH2 has superior controls and 32 player matches, which can be really fun.

However, the overall presentation and coolness of WaW tends to pull me back to it more. And I know the question you asked was about multiplayer, but when you tire of multi, the single player game is just light years beyond MoH2.
