Medieval 2:Total War.The Timurids. Full army, with over 5 units of Elephants, one of which has artillery, 2 units of rocket launchers, and crapload of elite cavalry. Very Hard Mode. No auto resolve. No artillery.
Making any kind of defensive formation is nigh on impossible, and don't even think about bringing any infatry, cause those fuckers can kill anything that isn't mounted in mere seconds. And the elephants are real buggers: In RTW, you atleast had incendiary pigs that could send them into a wild frenzy, but in MTW, you gotta kill them the old fashioned way. The only reason I beat them was because of an AI bug that caused their general to be in a unit of archers. And even after the battle, I had lost 3 full units of gold chevron lancers and had lost all of the 3 archers units I had used, and it cost over 15000 florins to retrain everything. The good news, however, was that after the battle, I had full control over all of northa asia, and only had the middle eastern and Italian nations to conquer.
