Anyone played this? Got it on a whim the other day and I've put something like 40 hours into it so far. It's quite addicting once you get into it. I've played Castile about four times now, only once getting to the point where I became Spain, and have kept on restarting. About to start my fifth attempt. The reason for my restarts is learning more and more about the game and realizing mistakes I made early on. This time around, I have a much greater understanding of the trade system and the buildings.

Any tips/tricks/techniques/experiences to share? After I get done with this Castiel play-through, I want to start another campaign as one of the smaller nations that are a bit more difficult.
