Germans are a OP civ. Just use the Settler Wagon its OP. They steal crates at 50 resources a grab! so place all your villagers on Food age up with wood + steal your enemies wood.
This gives you enough resources to build a mass of Pikemen+xbows+card uhlans.
Also on a side note don't make any villagers with Germany just ship the Settler Wagon cards, as it makes for a much faster rush.
