Environment: Heightmap generation and texture processing nearly closed. Though: Improvement of some shader issues and small details.
Wildlife: Passive animals like cats, dogs, birds,... Aggressive animals like wolves which may complicate the surviving in the beginning of the game.
World: Maps! On the one hand the sandbox mode maps list will be extended. On the other hand, the planned campaign will ship with a lot of unique maps. Interaction between these maps could be a coming feature.
AI: The main feature which is not included in the demo as it is under development currently. AOE like AI which builds and extends its own settlement, manages resource gathering and citizen labour, deploys units and fights the player.
Combat system: Under dev. Four different unit types (swordsman, pikeman, knight and archer), with three subcategories each, have been designed so far. Melee, ranged combat and siege are planned.
