Open Realms : Medieval Life is an open world survival game with RPG  elements that has a heavy focus on modular architectural building and a living world.
  The world is made up of individual "realms" that are each individually created part procedural and part handcrafted to give a unique and natural feeling.
 Each realm is filled with active wildlife and NPCs that work, fight, build, trade, and live like they would in a real world with a real world economy that is influenced by each players actions.
