great. i will start making the camp system (in top down pixelart), npcs and a basic tech tree for researching stuff to upgrade npc task efficiency
That sounds great! Bear in mind that the tech tree should be a culture tree too, so NPC/camp upgrades can be split across multiple cultures. For example, one which specializes in forestry, herbalism, alchemy, wooden constructions; another which specializes in stone, mining, metallurgy, etc. This doesn't need to be handled at the beginning, but eventually we will have multiple tech trees under different paths.
