I'd like to see more realism.

day and night cycles
. the villagers sleep at night
. this only works if the builders build enough huts

season cycles, and related, growing seasons
. must grow enough food to support population during winter
. must subsist on stored food and other sources when can't farm
related
. a skill for caring for and preparing stored food
. not sure what you would call this
. builders need to build more storage before food starts going bad

weather
. every few days everyone has to quit what they are doing and take shelter in the huts from the weather
. builders must build enough huts for these times or some of the population dies from exposure
. keeps you from growing your population too fast
. crops and berries grow faster after a rain so everyone should be put on food gathering for a day or two
