I have a complicated history with Borderlands, and I suspect that's a fairly common experience. Okay, so it's not all that complicated but bear with me.
I wasn't super into the first game. Sue me! "Better with friends" is an idiom/crutch that often rings true, but even with a full group, Xbox 360 communicator in-hand, I just couldn't get into the trash-filled landscapes and the roster as-is. Borderlands 2 was a completely different story, littered with colorful locales, more interesting classes and abilities, and a general sense of ramped-up lore that helped differentiate it from the pack.
Borderlands 3is the natural next step of that formula, but don't count on too many alterations.
