Seems like a really nice refinement of several things. Wonders are more wonderful now, many have gotten boosts. Like others have said, social policies seem really improved ... The pacing is nice and Honor is now much more useful as an opening branch. Branch finishers feel really natural. Combat in the longsword era is definitely changed. Crossbows are useful, and knights are more powerful in the open field relative to longswords. I like the improved variety there. Having great fun in my first play through.
