I've watched one test video of a magazine which has rarely disappointed me when following their reviews.
They said that the Warhammer recipe for Total War is the best yet.
Seems that a lot of design decision were made towards removing the biggest points of criticism for the former titles.
AI seems way better over all but especially during sieges due to limiting it to 2 walls of approach.
Same for battlefield AI overall.
Less politics and more tactic.
And a couple of other points.
For me those seem to be the right points of focus. Others will probably complain about removing depth in some areas.
Personally, I always and mostly enjoyed the battlefield part and even disliked all the diplomatic stuff for the most time. So I think it's gonna be a great game.
Pre-ordered after reading the review.
