Exactly. Just a simple script... For example, just to have 3-4 max tiers of camps. When player discover camps at first time - they are first or second level, but during the game they will build it up to 3 or even 4 tier, and maybe can recover destroyed ones and upgrade them. Maybe add some interesting stuff - like sending raids to nearby player base, like other scripted encounters. World of Valheim feels pretty lonely (no visible social interractions between mobs), nobody else chopping trees, build anything, even growing grain by Fulings is not real, because they not re-seed it or make new fields for seeding).

It`s not too difficult really, but can make game much more alive, because creatures like Fulings are supposed to be intelligent, but now they are just other brainless mobs. Maybe devs just want to be that way, but it would be much more intereting to feel that world around you is somehow evolving too.
