Monopoly and Risk.
Oh, these games have been the cause of SO many very, very loud fights between my brother and I. The last one was so bad we haven't played a game of Risk together in nearly a decade.
You should try Warlight. It's basically modern risk, on computers and such.
In the last few weeks of the school year, I started hosting games of it with almost half the class playing. So, so many times would there be a ton of different plots and such running through until it all blows up and everyone just starts destroying each other, and someone would almost always be caught in the middle with no allies and just torn to pieces.
It's rather amusing in Science to hear people shouting, "NO! GET THE FUCK OUT OF AFRICA!" as the rest of the class laughs because they just enacted a pincer move on the player.
It's such a fun but rage-y game, especially due to cards and such. You get cards by taking territories and they give you bonuses, like +10 armies this turn, or airlifting an army to a location. However, two cards known as Blockade and Abandon are so, so rageworthy. When you play them, you turn on territory neutral and it's armies quadrupedal. That means that if you ever have a chock point with the enemy quickly closing, you play this card and laugh while they scream and try to get past a 2000 strong neutral in their way.
Ah, Warlight. You are a fun game.
