Some interesting stuff in current game. I know the boat attacking a city's land units is fairly rare, but I've seen it multiple times now in one game. Germany attacked with 2 armies of cav at the same time, something I've never seen. I've always found AI armies to be fairly rare, and when you do see them, usually its a pretty silly combo on units. These were both full of cav, 3 cav each. Ultimately, still pretty stupid if left without defensive units to protect them, but potentially dangerous on offense. The AI dropping off multiple boatloads of troops at the same time for island attacks. Literally, multiple ships carrying troops. Maybe only 3, but 3 5/2 knights before gunpowder was a shocker the first time I saw it. Good thing I'm paranoid and overstuff my island cities with troops. Dunno how rare this is, but I made Berserks 3/2 amphibious available with Ironworking for Germany, Sweden, Denmark, and maybe France and Norway, and I've seen some single tile island cities fall to them (not mine, other AI cities).
