So, I'm playing a Poland play-through, on ironman, and I recently just got drawn into a war with Muscovy over the succession of Hungary ( They got it, I contested). I've won the war up to the point I can get the union; however, I am at adm tech 9, aka about to form the Commonwealth. Getting to my actual question, The decision to form the Commonwealth says fewer than two personal unions; however, I just wanted to be sure as this is an ironman game, does the game allow less than or equal to 2 unions, or is it a solid less than 2? This may seem silly, but I'm already bled dry on manpower and troops, and just called into a war against France, so if I can put them in a union and be safe, it would be very helpful.
