The combat is incredible; easy to learn but difficult to totally master. The story is really good, with great characters and often outstanding voice acting. The world is one of the most beautiful I've ever seen.
Everything outside of that? yeah it's fine. extremely repetitive missions and mission structure, usually involving just tracking someone to somewhere else and fighting off a bunch of Mongols. I really wish it was more varied because for me it wasn't a game I could sink a lot of hours into without getting really bored.
