Something something movie red cliff?
If you want to watch a good show about Three Kingdoms, then I recommend Three Kingdoms, the 2010 version. In fact, you can watch the entire thing with fantastic English subtitles on Youtube here:

As to why should you even be interested in all this, well... if you like Japan's Sengoku Jidai, this is basically that on a significantly larger scale with significantly more at stake. So much happened that two of the
minor characters are now revered as gods in modern day... for.... some... reason. Man, I wish I could be a rapist bandit and become worshiped as a god. Even China's own warring states era which established the Qin empire when people like
Sun Tzu and
Confucius were alive and doing crazy shit is completely in the shadow of the Three Kingdoms period. Actually, come to think of it, I never realized Sun Tzu, Confucius, and Lao Zhi were all alive in the same time period. That's kinda nuts. That's like Napoleon, Buddha, and Voltaire being alive at the same time.
Anyway...
There's a reason why this story is immortalized as one of China's three greatest works of literature and why there's so many games and shows about it.
Hell, even the Japanese play more Dynasty Warriors (Three Kingdoms) than they do Samurai Warriors (Sengoku Jidai).

I think I should stop talking about this though. I've gone super off topic.
To go back on topic, there's a super popular map compilation pack on Steam Workshop here:
http://steamcommunity.com/sharedfiles/filedetails/?id=877551324It basically puts in good community maps to replace existing maps for you to fight on in the campaign. I've tried it out and have had a hell of a lot of fun with it so far.
Though unfortunately, due to the map editor you still don't have walls you can deploy troops on traditionally and there are no gates or working towers. Still, I think it's way better than the shitty ass siege maps we have now.
