I'm not into PvP at all, but it wouldn't be true pirates that would have me running off to solo play only. I like the idea of piracy in the game. It's the "psychos" who get their jollies yanking people out of SC, blowing them away, then going off to find the next mark that would make me stick to solo. Some would argue that they're playing the "role" of a psychopath. Well, there's no universe either real or imagined where that would be allowed. What should happen is after the tenth or so murder in a short period of time, the next time the psycho goes into SC they're immediately interdicted and face a combined force of elite Imperial, Federation and Alliance police forces in maxed out Anacondas, Pythons, Dropships and Clippers who've been "hunting" this dangerous maniac since his killing spree began. From that point forward each and every time he goes into SC the result would be the same. He'd be yanked out and killed. The only way he'd really be able to play the game anymore is if he wipes his save and starts again. A maniac serial killer would not simply be givin additional minor fines in any remotely realistic universe, they would be killed, dead, forever, and wiped from existence.
something like that, if they are in a system where they are wanted
