28 hours later, and its done, I have a couple of missions to tidy up, and a few achievements, but apart from that, I think I am done.
Left with a slightly let down feeling, although ME2 is much more streamlined than ME1 was, I just feels a little "neutered" and a little less grandious in its scale, that said, its still a great game, well worth a playing.
Not sure if I am going to attempt another playthrough at insanity level or not......
