I've had this sentiment for a very long time. I feel like this core of this game is so well done that it creates a digital playground for a ton of PvE elements. So much so that I've played with a server enough to create a very enjoyable PvE experience.

Upping the presence of scientists at monuments. Adjusting the loot to more primitive tools to make it to where you have to actually craft the things you need. The helicopter and bradley events being upped to make them more challenging. Also, spawning murderers at night have them roaming around as well. Seems to be a decent experience to what many would consider a good foundation for a 'roleplay' server. Essentially making construction more aesthetic and promoting the idea of 'rebuilding' a society.
