The best thing is to wait and see how the game evolves. I already bought the DLC and I am looking forward to use.
Developers should be aware that older content needs a more significant update. I made a forum about it and the truth is I did not expect to receive so much support.
It seems that they are touching one civilization at a time, but there are things that must be significantly improved such as cattle. And with the opacity of revolusions, they must also be improved.
The revolusions improved a lot compared to the base game, it is time to take another leap.
