What do you get when you combine a Bethesda engine that, while janky, provides a lot of character interaction with the world and Obsidian's world building, flair for RPG systems and branching quests? One of the best RPGs ever made.

Witcher 3 is dripping with rich world building and well-crafted stories it does a fantastic job immersing you into the Witcher world.

Best RPG and open world in a very long time. Many sandbox games that I've played struggle to give you enough things to do to keep things interesting, not the case here. The emergent storytelling that comes from a deeply systems based game is better than most that crafted stories in other games.
