Damn, i got nothing new :(
I didn't see stone/metal storages for more/most capacity.
When you add nighttime u have to add lightsources too (torches or lampposts that needs coal as fuel and electric lamps for lategame).
And when there are hostile creatures we'll need military bots (melee+archer) to protect the villagers. Midgame military bots could have crossbows, shield/armor, maybe cavallary (horsebreeding?). Guns can be for lategame depending on the hostiles. ;)
