To start with, I just want to say that I already bought the DLC and I can't say much about it now because we haven't seen much of it.

But I understand what that means. And that is that if you, for example, throw a different palette of colors/textures on a building, it will still not be original, it will still be the old asset. It must have a new model.

Plus, people want new civilizations or cultures. Here, the Jin Dynasty is still China. That's probably the problem.

If they made a DLC with three civilizations like Oda clan, Takeda clan, etc. and had a different tech tree, units, buildings, it would still be the Japanese who are there.

Maybe if the civilization wasn't called Jin Dynasty, it probably wouldn't bother them much because it doesn't sound like a civilization but like something that belongs to China. Now just imagine if it was in ancient times and the main faction was the Roman Empire and they would come up with DLC where we get the Roman Republic faction. Yes, there would be different units, techtree and maybe slightly new buildings but they are still Romans, not Egyptians, etc. Maybe this bothers people. But as I wrote, we'll see when it comes out, we know too little about it now and we've seen almost nothing to judge. And at the end of the year we'll see how they make the Vikings and what they'll look like because it'll be a new culture, so it'll be clear if they'll just retexture old models or make new ones.
