Maybe you should play the SPD in 1914 and prevent WW1. Or play the SPD in 1919 and join the communists instead of sending the Freikorps after them. Or play the SPD in 1920 and use the momentum of the general strike against the Kapp coup to crush the Freikorps and have all the leading figures of the Conservative Revolution shot. Or play the SPD in 1923 and just kill Hitler after his coup attempt. Or play the SPD in 1925, not make von Hindenburg chancelor, keep the NSDAP illegal and disband the Stahlhelm and the SA.

This game actually gives you the choice to disband the Stalhelm but they just come back later anyway (at least, they did in my playthrough).
