I'm only a few hours in the Soroborean DLC, and I can tell that it looks like content that should have been there since launch and completes the game. It seems like they put a lot of work into it. The new area is fantastic and feels bigger/fuller than the rest, although 99% of the time it seems to be winter and snow. The new mechanics are great. There are new enemies, potions, weapons, equipment, recipes, etc. The music is also great. The new dungeon is huge, labyrinthine, and has tougher enemies. This DLC is worth it only for this dungeon. It also has its flaws that need to be polished. Recommended if you like the base game.
