Soon™ I'll be embarking on a new Edge of the Empire style campaign. The general overplot is that the PCs will be a mercenary crew working for a shadowy underworld boss. The boss has a Count of Monte Cristo revenge thing going on. In Phase 1 of the campaign, he wants to hurt his enemies - not necessarily outright murder them, though. He wants them to suffer; he wants them to lose everything as he has. His enemies are other powerful underworld types and powerful political types.
So I'm looking for some non-evil, non-assassiny/murdery story ideas. A few ideas I have already are...
Casino heist
Asset destruction
Ship theft
Intelligence gathering
Character assassination
What else can we throw into the mix? Also, in your opinion, what is the sustainability of this sort of campaign? (The PCs work for a boss as opposed to working for themselves.)
