It would been cool if we could buy property outside of towns, and build our own house there(like, able to choose between 5models of houses, and then choose upgrades for it).
Including ur own farm, and with farm animals
that would been cool, and you could hire a assistant to gather ingredients for alchemy etc.
Or even better, put in the ruins of a old village, with a ruined castle. Which you can buy and restore(with high customization), and being able to become the "lord" of the village, having people move in, pay tax to you if you hire soldiers to protect etc.. a side questline sort of. With lots of choices.
