Conquering Iberia is a complete nightmare. Not only does the game CTD every couple of turns, but the Luso's pump out stack after stack of cheap, plentiful, powerful, AP weapon-wielding troops that attack you in the mountains, forests, river crossings and cities. The terrain is tough, reinforcing your troops is next to impossible if you're the Romani (which I am right now) and even the militia troops take a bite out of the best of your men. It wouldn't be so bad if the Luso's didn't resist so fiercely, but I guess I asked for it when I became the Romani...
