I've been playing for a few hours now and I have to say that so far it's a lot of fun. The units look really nice, the economic side of the game seems pretty well balanced, and the AI in 1.5 works a little better than 1.2.

My favorite thing though has to be the traits and ancillaries. All the cool new pictures of general's retinues, all millions of different kinds of traits... it's pretty fun just reading about your characters. I'm gonna go play more and feed my addiction now, thanks EB!
