Defender's Quest: Valley of the Forgotten
Enemy waves march on fixed paths without adapting
Fallout: New Vegas

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Defender's Quest: Valley of the Forgotten
Wave compositions surprise only on first attempts
Fallout: New Vegas
