Borderlands 1 was a bit too slow both with the gameplay and the humor, this is obviously understandable due to it being the first game.
Borderlands 2 had humor that was really, really perfectly on the edge, the story was a classic freedom fighter story set in a bizarre sarcastic universe.
Borderlands TPS kept going with the same type of humor that B2 had but added a lot of fun backstory to Jack and the loaders/constructors.
Borderlands 3 took it too far with the toilet humor, and the whole social media storyline. At times it felt as if I was acting out a scene rather than playing a hero. Oh and I absolutely hated Vaughn.
