Things I'd like:
Weather, like earthquake, rain, tornadoes, tsunamis
Randomly generated dwarf towns underground that give quests, maybe?
More furniture items
Volcanoes and mountain biomes
Different continents with unique biomes: build a house near the ocean and a ship master npc appears that can take you to random lands about two size smaller than your original; crystal land, snow land, savannah land?
Different types of trees
Yeah, some wire reworking and more stuff to do with wires.
Some sort of NPC programming thing that lets you hire, say, guards for your castle and plan out patrol routes, or program a smith NPC to take materials from X slot in Y chest and make Z bars, then put them back.
Stealth mechanics? Probably not.
Crouching
Ledge grabbing.
More types of invasions, maybe a diplomacy option. Like necromancer army or legion of mummies.
