@Partisan: 

I'm the Co-Gm. If you want to have a Yakuza style gang, you can go right ahead. There is currently an Asian gang that was just created as an NPC. It has no name, no purpose, it's just there to be a filler. Basically, the Fallen Angels (biker gang) is selling guns to the Asians (Could be your gang if you want). They have a feud with the Russians who are trying to take over their territory. They also have trouble with the Africans for stealing one of their gun shipments. If you want that to be your gang that'd be awesome. But if you want to make a completely new one, that's cool too.
