Oh boy - another regency. It never ends, does it? Still, this would be interesting to play out in an exported game. With England and Scotland all messed up, Ireland would be in a position to do pretty much what she wanted. If you do, however, you may want to mod in some explorers and conquistadors. I would think they would gravitate there if Ireland was the strongest monarchy in the Isles, rather than as they did historically.
Looking forward to the last chapter of yet another highly enjoyable AAR, RossN.
