Got it today, I'm about 11 hours in. Having fun so far.
Both of us are playing as Claptrap so that has been... interesting, to say the least. I really enjoy Clap's action skill though, they way it references all the vault hunters from 2 was a nice touch.
A few things that bugged me were the voice acting and some of the quests. I find it kind of jarring that most new characters have Australian accents, not that it's bad, it's just weird. I've fond some of the side quests can drag on too, like the whole Pickle line of them. We finished the last one and goddamn I'm sick of the kid.
Waiting until we finish to see how it stacks up to 2, though.
