Fortunz is probably better to answer this, but since he hasn't i'll try.

The wii has an internal wi fi thing, so it's pretty simple to set up. i only played MOH Heroes 2 online, and it was a pretty standard. pick you game type, map, how many people etc...

wiis have friend codes so you can message other people on your list with wiis, similar to your friend list on xbox.

not all games are online compatible, though, just some. when i played MOH online, it did well. didn't notice many hiccups in gameplay or anything.

hope that helps.
