First of all just want to say I am loving the game. So now here is my 2cents.
I think some of the folks that leave the game early have the same problem I have with sandbox games. I love and hate them at the same time because I love the idea of it but after while having no quest I loose direction and loose interest. I don’t even want to get into how much money I have wasted on sandbox, survival games that I played for a few and left because I just got bored and lost direction.
I loved the objectives and that is the main reason I purchased the game so would love to see more of those.
I would also love to see player created content if that is possible. I would like to see a system where with enough prestige you can put a item in your building to designate it as a SHop, Tavern, Bakery, Farm that give buffs to players maybe. Even have a system where in addition to request baskets you can have player created contracts that others can pick up and do. Or some sort of contract system to have other pick up to help build up villages and towns. I think the possibilities are endless.
Oh yeah also implementing some sort of survival where you need to eat, sleep, and pay attention to weather and temp would also be nice.
