I had a good blast on this over the weekend. 6 hours in so far, and I've just completed the last story quest on the first planet. I explored everything, talked to everyone and got to level 10 prior to departure. I'm enjoying it so far, although I do have a few minor criticisms.
Firstly, Hard is too easy but Supernova is too difficult; shame there's no middle ground. Secondly, robbing people blind is still very easy and with high persuasion it basically negates any negatives of getting caught. Lastly, and I might have overlooked this, but there doesn't seem to be any way of determining if a weapon is "epic" / one of a kind. I ended up keeping a level 3 pistol, converting it to plasma and then tinkering with it. All in all though, a good game.
