Rogue Agent as a decent multiplayer game? I thought the map design in that game was god awful and the only saving grace was the traps, but okay. :P
Melee is enough on its own, and Double Dash is pretty good too. As has already been suggested, Mario Power Tennis is also good, pretty much the same craziness as the other Mario "party" games (not referring to the actual mario party franchise lol). I'd also recommend Wario Ware, but not the Mario Party games. Mario Party kinda got old for me at 11ish when I realised the board game part was shit boring unless something happened like stealing a star from a friend.
