If you drop some presumptions about the players you can go even faster--<p>Player 1: Roll a 3, 5, 6, 8, 9, 11 or 12. Don't purchase, so it goes to auction. In auction player 2 buys for 100% of their cash.<p>Player 2: Rolls a 4, lands on income tax. Game over.
The essence of the game is to show how important it is to be the one making up (or interpreting) the rules. Thus everyone has their own. The best rules include "take a shot whenever you roll dice, 2 if you get doubles" and "articles of clothing are negotiable instruments of exchange".
My favorite monopoly games are those where the players have played together before, and agree on a set of custom rules to the game in advance, and are fast-paced. I remember having rules added like loans and interest, and effectively unlimited freedom to make deals with players. Deals logged on paper, loan interest measured in turns and percentages, so much...fun. Actual fun though.<p>A game like this can even go fast paced where the next player is making their turn while you're still interacting with the bank from your turn, while someone else is calculating interest.<p>Doesn't sound fun typing it out but it was a blast.
This isn't a legal Monopoly game at all. When you land on an unowned property you have to buy it or auction it. "No action" is not a legal option.

Monopoly simulator is a fun little project. I had a very strange reason to build one once upon a time because a chef was doing a monopoly themed dinner and needed to know how much food for each square. <a href="http://blog.jdwyah.com/2013/08/the-statistics-of-monopoly-with-respect.html?m=1" rel="nofollow">http://blog.jdwyah.com/2013/08/the-statistics-of-monopoly-wi...</a>
