I like 3 Kingdoms, despite not being interested on it, i bought it and played.
It is by far one of the most polished Total War games, the game runs smooth and its very well made to run in almost every system.
It gives me a lot of Shogun 2 vibes, as that game was also a very smooth launch.
So i've been thinking. When the time comes for Shogun 3. I feel this game will be the standard to follow.
I can definitely see a lot of the mechanics from 3 Kingdoms being ported into Shogun 3. Specially the Romance Version.
Besides, there's also a lot of games similar to Dynasty Warriors set in the Sengoku Period. So i can definitely see it happening.
I don't see Medieval 3 or Empire 2 using a lot of the mechanics from 3 Kingdoms. But Shogun 2 and the potential Troy game, i can see it.
