I like the Campaign map as well but if that doesn't work too well it massively impacts the battles.

Also, how will factions that don't engage in the Industrial Revolution be modelled? The Ottoman empire declined throughout this period becasue of its inability/unwillingness to engage in the kind of technological and social changes happening in the West at the time. Similarly for the others - Persia, India, China, etc...

Will you be able to play any African nations?
