Do some of you people play prediction games here? I started a few weeks ago with Hollywood stock exchange and now I play some others too, it's quite funny.

Here are the sites I know:

- HSX you play with movie names or actor names, the stocks rise or fall depending on the box office Welcome to the Hollywood Stock Exchange - The Entertainment Prediction Market

- Sportdaq, you play with sport teams, sport people. Specially interesting for people from UK, it's done by the BBC BBC - Sportdaq - Homepage

- Trendio, here you can play with almost everything, politicians, diseases, places, celebrities, etc...
The movements of the stocks are more interesting than sportdaq or hsx because they are not depending on how much people trade them but directly on how often they appear in media. (updated
every 2 hours). http://www.trendio.com

They also have a wikipedia entry here Trendio.com - Wikipedia, the free encyclopedia

Do you know other ones?
