I picked it up and put it down a few times because I kept getting stuck and felt like I wasn't making any progress, but holy shit when I finally got a small amount of assistance from a friend and got things moving it was like an avalanche and it all unraveled magnificently.

The DLC was somehow even better than the base game by quite a wide margin for me, but I absolutely had to get help starting it because I couldn't figure out how without cheating.
