It would be nice to have a ingame stock market. As we have been told there will be corporations in the game, so why don't have a live stock market aswell. That way people can buy and sell into positions in the ingame companies. Would also be a cool thing if there were currencies and comodities to buy on the stock market. This would be very realistic and could give people opportunities too earn a good amount of ingame money fast (or lose!). I also hope that the bank will give people loans and stuff. These things would improve the financial system ingame and give more difference between poor and rich
