A really cool idea would be to treat it like a stock market where you buy stocks in games for a certain amount of units.
You earn by how much the game sells in a week/month.
GTA4 for example will sell much, therefore it should be a really expensive stock.
Unknown games should be really cheap.
It would become even better if everyone was forced to buy a certain number of games. That way you have to decide whether to buy 1 really great selling game and two really unknown or buy three medium selling games.
