Just cleared the game last night with full good karma. I had done nearly every sidequest i could find and started the main missions around lvl 15. As soon as i started to crack on with the main missions, i was disapointed, far too short and my lvling had made everything quite easy to dispatch with. All the hype of getting power armour died when i realised how close i was to the end of the game. Shame really.
For the record, i was on PS3, can honestly say it wasnt that buggy, just a few lockups here and there. And while the lack of no DLC does annoy me, it doesnt stop it being an awsome game.
