ok, i hope nobody steals this cause its kinda easy to do.
Its gonna be across from GTA and my own idea. You start with a zealot ( Thug w/ Knife) and roam around. You have to kill like 10 or w/e units to earn respect (exp) to join different gangs. But the more rep you have the more police go after you.
Then once you join, you can work your way up the ladder and become a mob boss. Then you can buy different weps like Uzi's (marines) and shotguns (ghosts). Also, i will make a basic commodity, weed. =) If you buy a dealer you can sell it to civs in the city or trade it or w/e you want to do. I will try to make it as open as possible.
If you have any ideas plz tell me.
