I don't think I've ever actually finished a game of Monopoly. Not as per the official rules anyway. We'd usually just set a time limit, and whoever was ahead when time was up was declared the winner. And I've only ever met one person who actually used the "auction" rule. Which is where any time any player lands on an unowned property, and they decide not to buy it at list price, it goes to auction, and whoever bids the highest gets it. This causes all the properties to be bought up very quickly.
But my main problem with Monopoly, is that if it's played by the "real" rules, the game gets very boring once everything's been bought, all the trades have been made and everything's been monopolized by somebody. Then you just go around the board over and over waiting to see who gets knocked out first.
I'm really disappointed Survive! didn't make it. He's a video explaining the current version, Survive: Escape from Atlantis. The original, which is what I have, is only slightly different.

So you have remember which ones are the ones worth saving, and guess, or deduce, which of the opposing players pieces you should kill off.
