Gameplay: It will be an infinite voxel world, where the player controls and recruits henchman to build a city and defend themselves from the world. The player will place "nodes" around the world to direct the actions of the NPCs, never having the ability to tell them directly what to do. The NPCs will have a variety of priorities than can be set (tree-cutting, mining, terraforming, building, farming, hunting, etc) and they will complete work based on these priorities balanced with their own wants and needs. The terrain is smooth voxels, and buildings will use minecraft-style blocks (with various materials and shapes). The catch is that players and NPCs can only hold one block at a time. The player will control the NPCs to get the heavy lifting done, which leaves him/her time to explore, scavenge, scout, defend, or raid.
Adding some new images of my new trees. Game updated to Unity 5.3.1 recently.
