[OnChkMnDS]

I just got an edge card + I had a wii

I got:
SSBM
Bomberman Generations
ToS
Godzilla: DAMM

I had:

Mario Party 4
Custom Robo

TimeSplitters 2/Future Perfect are great FPS. FP has longer load times, better textures, a story that sort of makes sense, better mapmaker, and better co-op(2 player only) TS2 has better maps, less generic characters, better cheats, and a better multiplayer in general.
Double Dash
Super Monkey Ball 1/2
Pac-Man Vs. is wicked fun, but needs a GBA+GBA->GCN cable.
WarioWare. Nuff said.

Red Faction 2 is also a quality FPS. Nothing spectacular, but I had hours of fun dueling friends from the opposite side of the map with the rail gun. Rogue Squadron 3 had some fantastic 2-player co-op. Mario Kart is always the multiplayer game of choice whenever my brothers are around. Don't expect that much multiplayer value out of ToS, as the camera can be a little crappy for people that aren't player one. F-Zero GX, while a damn cool game, had a very poorly implemented multiplayer.

X-Men Legends/Legends II are good, if you haven't played 3/4 player on another console. The Super Monkey Ball 1/2 minigames (and the main game, to a lesser extent) are also good (Monkey Fight is always good for 30 minute sessions, especially with 4 players).

Those are two series off the top of my head.

I usually have "gaming nights" with 3-4 other friends every Friday so I got quite a few 2P-4P games. We always play the Wii/GC, Xbox, and PS2 eventually through the night. They're casual gamers FYI. Gamecube MP games I have are:

Bomberman Generations (Borrowing from another CAG'er)
Mario Kart DD
Mario Party 5, 6, 7
Mario Strikers (Though, I just got the Wii version so won't be needing this)
NHL Hitz 2003
Pac-Man Vs.
Sonic Riders (Actually, haven't opened it yet and don't really want to play it)
SSBM
Super Monkey Ball 2
Warioware Mega Party games

Ones I don't currently own but are fun:
Bomberman Jetters (Though since you have Generations, don't get this)
Final Fantasy: Crystal Chronicles (Don't have 4 GBA's)
Mario Power Tennis
Super Monkey Ball 1
Zelda: Four Swords (Don't have 4 GBA's)

What console exclusive games that are 4P haven't I added?

f-zero is an excellent 4p game, but its not really friendly for newbies
donkey konga 2 or 3 (you need a couple of bongos though) and
soul calibur II (only 2p though, Link as an exclusive is worth the price of admission)
