Gangwarzzz
In this game you the player must create a gang and manage it by using RTS controls. Gangwarzzz will be an mmo so you can play against other people from around the world (similar to how those facebook games work); or you can set up a private game with some friends. At the start of the game each player has only a few members as well as a couple streets in a city which are under their control.
Players can control their gang members and send them of on errands RTS style. These errands include recruiting people to join your gang, selling and doing 'deals'. Intimidating important people to gang more influence in an area etc...
You can also get involved in the black market to arm your members and send them of to battle other gangs. As members gain experience they will become prominent people in your gang and will eventually become a champion with abilities. These abilities are determined on the character of the member and what he/she is experienced in.
Each gang will have a net-worth that determines the value of it assets. A game can be won if a player's gang reaches a certain net-worth or if it has a pre-determined amount of the city under his control.
