Both the chinese and the indian walls have some Christian crosses which make them look really odd. They should change those symbols to something more appropriate for their culture.
I say christian because their sides are not isometric, the horizontal line is a little higher. Thats how christian crosses are to resemble the crosses of crucifixion
Exactly like AoE3. It should match the aesthetics of the game more.
They are oversized but also fire at a really weird speed.
