It is almost universally agreed that Hitler lost the war when he invaded the Soviet Union in 1941. The second most egregious error IMHO was not taking care of Gibraltor and the Suez Canal, thus allowing the Allies to dominate the Med. Third was not focusing when he did invade the USSR, and many agree that he should have been focused on Baku and all the oil and mines in between. in 1941 the SE of the Soviet Empire was the only thing worth focusing on after all the manufacturing was moved to the Urals (which, by the way, was an incredible feat).
So I would say that your opponent is a good student of history and you're in for a hard-fought game.
The Spanish Gambit is a very historical possibility and should be in the mix or the game is not valid. It was one of Hitler's choices and probably his best one.
I have been working on mods for both SC3 Europe and WAW as well as WarPlan that starts just after France surrenders. I hate slogging through the Polish and French campaigns just to get to the point where most of the choices open to the Germans are available. Batte of Britain, Sea Lion, Vichy, Barbarossa, Gibraltor, North Africa, if and when to invade the USSR, go north or south if I do, etc. all start with decisions in 1940
