Normally in EU (and most strategy games), the play's faction/country is something of a snowball that gets progressively larger - perhaps hitting a momentary bump or snag here or there - but for the most part onwards and upwards. In the evident of a player implosion (or sometimes a momentary bump or snag) the gut reaction is to reload a save or quit the game. I would love to see some way for EUIV to emulate the decline of a player's empire in a way that's both fun and rewarding (i.e. not soul crushing).
Perhaps there is a way to implement a sequence of events that changes the player's focus from glory and expansion to OH MY HEAVENS! SAVE THE COUNTRY! What I'm thinking here is that just like growth is almost inevitable normally; for a declining country, contraction would be inevitable, but give the player certain objectives or let them focus on staving off certain blights. Perhaps Poland is being threatened with invasion by foreign powers, rebels wanting decentralization, and a spreading heresy. The player would only have the resources to focus on one, so during a succession of wars, she would have to cede chunks of her kingdom, and offer religious tolerance to the heretics (increasing stability costs and leading to new branches of more diverse heretics). "Succeeding" wouldn't mean centralizing, but rather decentralizing a little as possible.
