I saw the December issue of PC Gamer (US) in my doctor's office and they have a review of Medieval 2.
They give it 90%.

I didn't have a chance to read the review, but it's several pages with lots of pics.

gleaned from the first couple of paragraphs:

"bigger, prettier and more addictive"
AI is very good, but can be inconsistent

perhaps someone who has the issue can give a summary.
