Actually watched QB's twitch stream playing this and it looked brilliant, I couldn't see any glaring problems. Look's polished and stable, really looking forward to it now.
Gotta admit, having watched some Twitch streams in the last 48 hrs I don't see any glaring issues either, at least on the single player/campaign front. Looks reasonably polished and fun, with a good emphasis on the battles themselves, which I think is a good thing for a Total War game. I haven't come away with the impression that the strategic part has been streamlined to oblivion ( contrary to the RPS review ).
