The Brandenburgers are not too difficult - I found Wuerttemburg to be the worst german faction to play.
Those swiss rebels absolutely destroyed me on the second turn.

Tell me, AlexandersFolornHope, are you witnessing problems with the unit graphics in battle?

Are some of them invisible or very distorted?

My favourite faction was certainly France in that game, where as usually I would play a smaller, discreet faction in other mods.
