Well I finished Anniversary earlier today. Over all, I'm very happy with the version. It looks absolutely lovely, love some of the redone sounds (especially the Ghost weaponry) and I the soundtrack sounds as lovely as ever. Don't know about anyone else but is the lip-synching out for the new cut scenes? That'd be my only complaint, really.
Going through picking up some terminals I've missed - which rock btw. Absolutely love them. And nice to see the continuity between the terminals and Greg Bear's books. Really made me smile.
Need to do all the co-op stuff though.
