From the videos and previews they gave us, the AI keeps doing the same thing as in Warband, that is rushing you down and spamming attacks on you.
Blood splats on armours, horses, weapons and such.
More realistic citizens, more "medieval fantasy type of" town (ppl brawling in the streets, drunk folks who pissed themselves knocked out on the streets, random put things in the enviroment, procedural situations and whatever)
Let it be alive, something absolutely gorgeous, something that we feel, something that we imagine.
Warband did that, and we want that same sensation again. And not just a re-skinned Warband ffs
