Arms dealing seems like a bit of a narrow field in this sort of setting, at least if every single PC is going to be one. Would it be unreasonable to widen into other sorts of smuggling or criminal activity?
The RP is going to be told in chapters, we're moving away away from my usual open world settings, for the time being. There will be a beginning, middle and end with the potential for other stories being told in the world at a later stage. For this reason, all PC are part of the same smuggling ring.
^^ I planned on crafting a thief/rogue sort of character
There's no reason you can't make a thief/rogue.
On another note guy, the role-play is not going to be operating on a first come first served and while a player cap has not been discussed yet it should be noted that CS' will be accepted on a number of criteria to be expressed in the ooc.
