This is a relatively new Role play game, I happened to stumble across it in my search for a good game to play. Unlike most games of its kind it is not turn based!!, although it is not turn based strictly speaking, there are restrictions to what you can do each day. You need money to make money in this game, but after your first couple of days of playing you should have fairly deep pockets.
This game is highly addictive, and will burn up alot of your time.
