This steamer looks much better, but is it possible to enlarge this turret? (I know it is now perfect in scale to the original, but it is hard to spot that it is turret here due to bright yellow details).
Meanwhile I added new type of roads to the augmented2 longturn branch.
There are two reasons, one is to adjust infrastructure to longer game duration, second to lessen effects of making roads just before turn change
(similar to fort/forstress, you need 2 turns to have fully upgraded road).
Road upgrade system is now as follows:
Unpaved roads (+trade, speed x2, native for infantry/cavalry) -> Roads (speed x3, native for all land units) -> Highways (speed x6, +25% shield).
Railroad is a separate upgrade parallel to roads, it gives infinity speed for Trains, Small Land and Merchants and +25% shield.
I need to fix offset of railroads and highways - highways should hide roads, while railroads should be parallel to them both,
it is opposite now.
