Okay, i LOVE these ideas cuz i LOVE farming
I think i already suggested buildable wells and blacksmith workshop stuff...
Crops that need more RL days to grow are a wonderfull idea
but make it so that the plants cant be stolen by someone else, and the harvested stuff should actually give a reasonable ammount of plat, not only 2 plat and 5 silver...
Satrek's idea is also great (i think it has also been suggested yet)
C'mon Stef, its almost christmas

And like Zurk, i will re-upgrade in 85 days (when gold runs out) if you add this
