That's a good Idea,
I haven't played Rust, ARC, or Conan, but even with better PvE, the game would be different enough, as the survival is mutch better
It would be neat if you could then lead the settlement to war agents a boss, just be sure to make the boss
take longer then 15 minuets,
no be to easy,
not make us fall asleep grinding,
if you fail not to have to start over again,
and in more then one fight
Ideas to solve those are to:
create multiple enemies, and killing enough of them would weaken the big one.
I hope that bringing civilization back isn't impossible to code!
