speaking again of the old PSO servers, but in the first version (i think, my memory isn't so great. D: ) there was the problem of hackers getting into your game and killing your character. as you'd drop your equipped weapon and meseta when you died, this was a big pain.

had a hacker get into my party a few times. each time we'd panic and disconnect as fast as we could before he could do anything. this is why i'm against general PvP, just from remembering what a pain it was to have to drop everything and try to get to the save/logout option before they could nuke you. :/

so if PvP was to be considered as a serious option, perhaps the best idea would be missions only, like the hoverboard racing and etc. I'm with what seth astra said.
