Boarderlands 2 was a great looter/ shooter. You could farm things you wanted, so much variety in guns. The sniper rifle that would try and give you a guilt trip for shooting people was hilarious. I remember having one pistol that shot a spread of 8 pellets and if you shot directly at an enemy it did jack all damage, but if you got close and ricocheted the pellets off the ground it did massive damage, just melted everything. It was from the mission you had to collect body parts for the loader bot that wanted to be a human.
Borderlands 3 was terrible. The gun with legs was cool though.
