I've play this game multiple times with each update and then some, also with friends, and I notice the same thing happening. We all kind of camp around the first trader. There doesn't seem to be any kind of incentive to travel further beyond the starting area. We can farm skill books until they're all collected since quests reset poi's. There's is no real incentive to build a base since on day 7 we all just camp on the roof of a preexisting building. We've literally just built storage units outside the trader.
My suggestion is to have different tiers of skill books. The starting areas should have the initial tiers and the city should have the highest. The game progression could start in the forest and eventually conclude in the city where players could collect the highest skill books allowing for crafting the best weapons. I would also suggest top tier weapons to have mats which are more rare and located only in the high level pois. This would require players to actually try to farm the higher pois for endgame parts. Currently, everything a player needs to craft, high end gear they can literally find in the starting area which cuts the game and the fun short.
