My thoughts on the ideas are the following, germans should have wonderful infantry, good cavalry and artillery but be very expensive, japanese should be similar to the germans but with weaker infantry/ artillery but better cavalry, also slightly cheaper units, if implemented ottomans should be very cheap other then elite gunners(the jannisaries) and be based on militia like units spamming the enemy, after all that was usually how ottomans won battles, by sheer weight of numbers
ok, here's how it goes:
Germans - fantastic range infantry, amazing artillery, ok cavalry, but most expensive of the three factions (i still think they should have the balloon, even if it was invented a few years afterwards...think gameplay here)
Japanese - greatest melee infantry, range infantry are pretty good, average calvalry, pretty average costs.
Ottomans - everything sucks (except for the Janissary, Elephant artillery, and their cavalry), but have really well priced units and fast build times (perfect for spam)
can we agree on this?
