It’s punishing. Some design decisions (such as having to drink a potion to save the game) make it so that it takes comparatively longer for your character to become a “superhuman” than it would in Skyrim or Fallout. Worth it if you liked those other two!
Kingdom Come: Deliverance. Loving it, really hard to get over the initial difficulty curve, but all the more satisfying for it. It’s like a AA version of Skyrim, with some elements where it’s even better.
