Multiplayer games that are blood boilers

I'm sure there are many of you who play multiplayer games that fun is had by all, but there are also a few that end in controversy every time and simply cause tempers to fly.

Since fighting games are never a staple when we all get together (shame on them) there are multiplayer games that we played or play frequently that is simply good fun:

Mario Kart 64
Outlaw Volleyball
Goldeneye 007
007 Nightfire
Tiger Woods 2003
NHL Hitz 2003

Of course, the games we played most often are those that always seem to end in controversy and are also bonafide blood boilers:

Risk (Genesis)
NHL 94 (Genesis)
Halo

and the game we play most frequently lately with no signs of slowing down:

Def Jam Vendetta

Actually, all the AKI wrestling games we're like this, WCW/NWO Revenge in particular.

What games cause havoc in your circle?

mario party three, and halo is all we play when all of my buddies and i get together, i hate halo, but mario party 3 is nice as i always win.

Soul Calibur 2. Especially when someone loses to the "one-handed" or "one button" ultimate humiliation.

Controllers get thrown.

when i have buddies get together we usually play super monkey ball,super smash brothers melee and powerstone 2 any bomberman is fun and i always break out off-road or super offroad for my nes or snes

SSBM, people get pissed when I beat them. They don't complain until I start to talk shit

SvC. I'm a huge fighting game fanboy so it makes me very angry when someone is able to dodge a fireball by kicking it or some shit. It's fun an all, but it drives me nuts sometimes.

Mario Party makes me mad because I always lose at it, much like Monopoly. Though that's mostly because you end up spending a whole lot of time playing those games before you realize that you're just getting screwed.

Worms

Its just one of the greatest games ever, and should never be messed with or upgraded.

Soul Calibur 1 and 2

No other game has ever gotten so intense as this when I play with my friends. SSBM and Mario Tennis have come close, but not quite.

Halo is by far the most popular multiplayer game amongst my circle of friends, but we just get really into it, never angry.

HOW.EVER. There a few titles that I've seen arguments over, shouting matches, even violence. These titles are:

-Starfox 64 (someone threw a controller at the winner)
-Super Smash Brothers (people have left the house itself in disgust)
-Goldeneye (shouting matches)

AND THE ULTIMATE FUCKING BLOOD BOILER:

VIRTUA TENNIS.

Ask Kid Aphex. The most EPIC argument ever CONCIEVED took place after a round of this game. Fucking scary.

Death Tank Zwei for Sega Saturn <--- BEST multiplayer game ever, and always causes tempers to raise whenever it seems certain players are being 'picked on'.

Virtua Tennis, back in the days where my friends and I would play a ton, would get a lot of people mad. We would play two on two, and there would almost always be somebody mad about something (it's always the teammate's fault). Both games on the DC were/are PURE GOLD.
