Given that 1 is really not possible or designed to be part of this game, player retention rests on 2. Give PvE players the ability to meet friends and form bonds, and the player base will reward you with their loyalty.
I agree. It is not unreasonable to call sim games the "ultimate" form of RP in an RPG since that is the driving force to play. As it stands, if you for what ever reason don't like PvP (at least in it's current state) then most of left to play solo/with IRL friends. I go on the forums from time to time and it is only just recently (this thread) that I even discovered the mobius group. If there was an open-PvE, imho, I think it would just mean people migrating from solo/group play to that one, rather than people going from open to it. So the open-PvP population would not suffer too much. And honestly I think the thing that keeps people away from possible PvP zones are things like very mild penalties for killing players, inability to hull tank thanks to armor doing for what ever reason NOTHING to protect internal subsystems so once your shield pops it could be game over in just a few sec, etc.
On a side note though this game is still in it's infancy. Even with PvE it's really just RES hunting. Missions are boring and unrewarding. With the exception of trying to solo/duo SSSs there is no difficult but rewarding forms of combat. Once you get a viper you can pretty much do everything with ease. "Better" ships don't help much because the ceiling for combat is so low right now everything is a joke with the exception of PvP. I know an Open-PvE mode would not be really hard to make, but as it stands I am struggling to find the point of joining a wing beyond the social aspect of it.
