I played it for 3 hours last night and its like borderlands 2 with the additional gravity effects, an oxygen mechanic and new characters and abilities. I enjoyed it and I'll probably chip away at it like I did borderlands 2 because I enjoy the humor and the universe. I made a gladiator and got around level 6 primarily with melee, I also tried out claptrap for 5 levels and his skill trees are a little abnormal - in a good way, I tried Nisha and her ability so far seems to destroy mobs extremely quickly, I was least interested in Wilhelm and I didn't play him too much.
