Me and my sister, occasionally my brother, used to play WII multiplayer religiously. Except we never fought each other.

We’d set up as enemies, enable walls, and then each pick our favourite peon and peasant. We’d stick them together (being the only class that doesn’t actively start attacking each other when together), build a wall around them, and name them (almost always Tom and Bob, or Tom and Joe). Then we’d build elaborate mazes and circuses around that box, usually with a gladiator ring to occasionally send enemies into to fight. Anything was game, the only rules being Never Kill Tom and Bob. The box around them, of course, was to stop enemy troops from auto-attacking when they got near.

We’d pretty much just cover the entire map in wall-mazes and designs. Sometimes cut mazes into trees.
