Mutual Mania: Volatile Markets is a d100 based modification to Mutual Mania. The rules are simple: remove the World Event and Personal Event cards from the game. Whenever a player lands on a World Event or Personal Event space, that player rolls a d100 and consults the chart to determine what occurs.
Note: The "Insider Trading Token" allows a player to sell that percentage of a stock as an interrupt. That is, if Emerging Markets crashes, you can sell a percentage of your stock in Emerging Markets at the pre-crash price.
My friend and I made this modification and we think it makes the game a LOT more fun. Mutual Mania is not a great game by any measure, but if you are looking for a quick luck based stock market game, this modification make Mutual Mania a nice light treat.
It is recommended that players determine end game conditions at the game start. Some examples we use are: x number of markets have crashed; 1 hour of game play.
I hope someone gets to try this and finds it an enjoyable improvement!
