Try even smaller maps. Try giving yourself artificial limitations to make games harder, like role playing justifications for army leaders, having a decadent leader who keeps his elite guard at home patrolling rather than fighting, that sort of thing.

Try NI (no indy) versions of maps.

Stale for 5 turns at the start of every game.

Force yourself to make use of certain pretender choices.

See if you can win a game with all negative scales and an asleep pretender.
