Mount&Blade is a 3D, open-ended, single-player, third- or first-person, computer role-playing game, created and distributed by the Turkish development house TaleWorlds. Mount&Blade has a medieval setting, without any fantasy elements. Mount&Blade is notable for its emphasis on realistic cavalry combat, which was common in the era, but is largely absent in most RPG titles.
The Peasants mod allows you to create your own village, build some houses, resource fields and more.
