I wouldn't call it boring, it's probably because dynasty warriors made their names so well known. And yes, it would be interesting, but by the same hand it would be disappointing not to be able to guide Gan Ning's sword though my enemies lungs personally, as I've become accustomed to with him.
I actually always was hoping for Shogun 2 to be next after Empire, except that it included China and maybe Russia. I was sad it didn't include anything but Japan, but it still looks great, just hope they cover them at some point in time. The problem would be making it different than their other games.
It'd be sweet. More troops and more gore in the battles. From the Han Dynasty (beginning of the 3k period) to the Jin Dynasty (the end of the 3k period) there were like 30,000,000 deaths, largely because battles had hundreds of thousands of soldiers.
In one instance, in a naval battle, one warlord's entire fleet was burned and he lost almost a million men in one fire attack.
But it could add duels into the series. Historically, dueling wasn't quite as popular but in the novel about the time, duels happened quite often. It'd be great to see Guan Yu and Lu Bu duel in a total war game, then have the infantry and cavalry crash on each other.
When you romantisize such things as war, the numbers tend to get embeleshed. I doubt Cao Cao had 1 million soldiers/ships at Chi Bi when he lost his fleet, but it sure makes one hell of a story though doesnt it.
