If they do add in something like hungry muggers or something, I'd at least like the game to give you options like:
1. You've made the mistake of picking a fight with the wrong people. [Fight!]
2. [Intimidate] We've killed dozens of men stronger and better equipped than you. ( medium Situation bonus)
3. [Charm] Come on, let's talk this out. It'd be a shame if your face got all messed up. (Situation Penalty)
4. [Reason] We're Source Hunters. If you fight, you stand no chance. (small situation bonus)
The bonuses grow (and the penalty lessens) as the size of your party increases. If the check fails, a fight starts. There, a mugger fight that exists but can be avoided.
I'm not sure where it would go though, you'd have to do some rearranging of the town and probably much more. (Which might not be a bad thing as it would let them put a waypoint in by the market.)
I'm not sure that muggers would fit though, certainly not with the legion patrolling constantly. My objection to adding in something like this is that it could lead to requiringmore changes than you'd think.
