Ok, I know, great graphics, sounds, lanscapes, castles, etc. but AI is not very challenging.Sieges are dull and I often press autoresolve button to skip them. Diplomacy is slightly better than medieval 1 but still you can be backstabed by your long time ally only because you have 1 unit in border castle. AI in strategy map (especially moving armies and attacking) colud be better. I suppose that improvement of battle AI is harder to do but actually it is almost impossible to loose battle with equal opponent. Additionally when troops are under heavy rain of arrows and units are melting down in numbers quickly why they still stand still? They dont even set loose formation(except archers). Morale of medieval warriors wasn't so high as we know.Enemy cavarly is not flanking-they always attack middle units of my army or cavarly standing on wing.Ok maybe it is too early period (I'm in XIII century now)maybe they will get wise later :)
