Right. I've been wondering. When would be the best time for Prussia to expand into the Baltics? Preferably, I'd also like them to have Brandenburg and Silesia as well.
In short, you're to make it as large as possible before(if it does at all) unites Germany. But I'd love to see how Prussia might come to control the European Baltic coast.
One more rule: No unions with Sweden unless it's under Prussian dominance.
