What about that:
- make something like GTN, but with bounties and what about bountyhunting other players ? Someone will put bounty on your head, you can pick that bounty a try killed that player. If you fail you bounty rank will go down, player who survived attack will get some kind of "get out of jail free card" and stuff like that. I think, this is really fun
- or what about real smuggling. Make some kind of mines on some planets. Let guilds fight fort that mines and smugglers/agents smugling goods to Nar Shadda. Smugglers will get some heat, because of smuggling and become well known, for thier "profit" so, other players can stop them from smugling.
Yeah, i know it sound kind weird, but it could be fun
