I recently got into Europa Universalis IV. Things are going well for my first game. I started as Castile and diplomatically formed Spain. I am the world leader in colonization in the New World. France stands at my back, and Portugal is slowing being dissolved into Spain.
However, the Protestant reformation has started, and, well, it is hurting me some. We Spanish pride ourselves on your Catholic faith (we are even the Defender of the Faith), but it hurts our relations ship with many other nations and our research (or was it idea group?) speed. What benefits do the Spanish people gain by remaining Catholic? It isn't papal influence since the Pope isn't as powerful as he was before the Reformation. The only major reason I can see at the moment is that it would hurt our relationship with France if we became Protestants.
