If you want to play a beautifully crafted, *real* medieval roleplay game, then you should definitely give Kingdom Come: Deliverance a go.

After a rough launch, this game (even if not bugfree) is now much more stable. You play the role of Henry, the son of a blacksmith, a peasant forced down the path of adventure. You will experience all the growing pains of going from zero to hero, and feel yourself improving at every adventure, challenge or task that you encounter. Lots of very original, hard but rewarding profession systems put together to weave this immersion in which you will spend days on. There is some bipolarity on this game, where you sometimes experience fantastic and original sequences and then some dull and unuseful moments.

Definitely not a perfect game, flawed by some lack of polish, and sometimes bad pacing, but still a gem that can't go unplayed by fans of history and medieval roleplay.
