My sim is being built as a portfolio game, and is still in the early stages. It is going to be a layered goal based AI for most actors, while the player gets control over one family in the settlement. So, no links or anything yet, I'm still picking away at some of the core mechanics as there are a lot of little chunks I need to work away at. (Things like the tiling of the map for LOD, and procedural generation of building designs. It is going to be a free placement/movement map with a hex/triangle based height map for terrain.)
