So let's do it !We had India in 3000 BC, then it was moved later, and then we got Harappa as new 3000 BC India.
We had China in 3000 BC, then it was moved late, and now we need something as new 3000 BC China!
Shang civ. Spawns at 3000bc in Yin (chinese version : Anyang).
Core area : well, maybe like the current chinese one, but a little smaller.
While our classical chinese civ would spawn at 1200 BC in Fenghao (later Changan and Xian) with Zhou dynasty.
Shang's game mustn't be late, because of the Zhou and flipping cities.
