The game goes beyond being barbarian right?
When you evolve your weapons and armor, you should also be able to improve technology.
You evolve your diplomacy too.
In the lights of me loving the game too much and actually wanting to participate in its improvement. I believe that this does not seem too exciting at the moment since there are much more stuff to work on first, but I thought the idea might be appealing to some people and I certainly wish to help with ways to increase player numbers.
We have seeds. We need a better farming system. Like a mini farming simulator game?
How about husbandry? Maybe add cows, sheep and dogs to the game?
Farmer thralls? Guard dogs?
