Man oh man, I did not expect for the story to be this depth man. This is too much lore for borderlands standards, but like, damn is it well done. The pacing needs a little getting used to because it's not your usual borderlands narrative, but once you're in, you're in. All the references and mechanics from the main game translate well enough for this story driven experience. Multiple play throughs are a must.
Edit: THE CINEMATICS ARE CRAZY GOOD.
