i didnt much care for pre-sequel or 3, but Tiny Tina's wonderlands is out now, and mixes in magic with guns. Looks funlately it's been Borderlands 2 and then just recently I switched to the Pre-Sequel. I only get to play about once a week or so, so it's easier for me to stick to old familiar favorites otherwise I have to spend forever recombobulating myself/remembering what I was doing (also re-playing stuff over and over again is how I roll anyway, but I never did finish the Pre-Sequel when I played before so hopefully I can this time)
2 was definitely the best of the bunch by far.
