Just fyi, I just wrote this response and the damn forum timed me out, so might be a bit abbreviated this time.
Game is epic. Great to have a game with so much hype finally be satisfying. Maybe my favorite FPS, after Goldeneye 007, perhaps :D.
Only thing that isn't cool is I don't have any friends to play with online :(.
But slaying 'em with Axton, level 17 right now :D
Side quests aren't very interesting to me though, which is a shame. But that not too big a deal.
