I think that it would be a great idea to make a game about English Civil War with Olivier Cromwell https://en.wikipedia.org/wiki/English_Civil_War
. This period has a lot of potential, and unfortunately there are few games about this century. If this game would be good, maybe there would be a chance for a big Total War game in the time of 1492-1699.
I hope to see battle like this in the game!
Another good idea is game about Wars of the Roses in the end of the Middle Ages. https://en.wikipedia.org/wiki/Wars_of_the_Roses
Third idea to game about Renaissance Italian Wars. https://en.wikipedia.org/wiki/Italian_Wars
What do you think about it?
