Why build crossbows instead of skirms in Age 3 when you already have big rgold reserve/income?
Priests are useless 99% of the time (only worth if you have low hp artillery or mamelukes)
Need a better deck, lack of age 3 cards and lack of wood resource shipments slows down your eco significantly (Wood is the slowest resource to gather in the game).
You spent 2000wood on mills/plantations within first 20 mins of game, that’s a huge cost for so early in the game. At this point, Germany should chewing mines because its quick gather rate instead of slow ass plantations. If you wanted a better greed build you should have spent 600 of that wood on a second TC so you can bump out double the amount of settlers, combine that with the card that lets you train settler wagons from mills.
Use attack move when using hand inf/cav, better movement and less wasted time clumping after one target.
Start building walls earlier, since its treaty you know what time the AI will be there.
