Easily the best story in the franchise. Anthony Burch did a great job. If you want something else great that has him at the helm, check out his dnd podcast: Dungeons and Daddies.
This is also the game that gave us the character voiced by Ashley Burch: Tiny Tina.
The gameplay is more of what was in the first game, but better.
This is a super fun game and probably the best in the franchise.
