Additional praise and critique
The grand strategy side of M2TW seems to have recieved the most love. The campaign map AI (CAI?) is superb. It doesn't let me get away with anything and launches devastating land and sea invasions with balanced armies.
It's great for the most part. I have noticed that an interloping neutral army--maybe the remant of a crusade--often comes to squat on my land, meandering around the coast as if waiting for a lift that never comes. The AOE of the hapless foreigners can block my movement, but otherwise they do no harm. The lack of military access perhaps strands them. Or maybe they prefer the shores of Genoa to their sinister paymaster back home. I only wish I could charge them rent.
