Still in Early Access, Three Kingdoms:The Last Warlord seems to offer a different take on that period than the Koei games.
Aside from the usual EA issues, it’s a port of a Chinese game, which means the manual, website, and most of the Steam forums are still in Chinese. Plus there’s no tutorial.
If I had the time I’d grab it and figure it out on my own. But I don’t, so I’ll just wait.
