The idea is that everyone exists in the same world and shares the same history.
Such a world will have all types of people. Including unsavory types like murderers and thieves.
If a player is not wanting to share the experience of this single world then honestly they may want to pass on this game.
IKR who would be such a delusional bastard for removing 70% of the content of the game by making it a PVE game. Lets be honests here, mortal online PVE is absolute trash, player interaction is about 70% of the game. And people want a pve server for what, for hoarding simulator? for killing razorbacks un-altered by some nakid bastard with a shortsword?
Come the fuck on people, theres not that much PVE nor its good quality content for you to enjoy it. Insisting on the subject won't make it real, people have insisted on quality changes for MO1 for over a decade and that shit wasn't ever addressed, so news for you this doesn't even go near the radar of SV, quit asking for dumb shit and if you do have a good idea on how to make PVE something better than the bullshit it actually is i encourage you to post it in the forums.
