I have recently begun playing Hollywood Stock Exchange (HSX), which is an online simulation of a stock exchange based on Hollywood. Instead of trading shares of a company you by into Movie Stocks, Star Bonds, Movie Funds and Derivitaves.
You begin with 2 million H$ and invest that to make money. A couple of things don't align themselves with the real world, long term investing is multiple years, but rather in most cases multiple months.
The one discovery I have made is that it is not a good idea to invest in movies that I think look good, because evidently I do not have the same taste in movies as the masses.
This is definitely a fun game to play. If you join, add me to your league (rugby148)
