Walp, I finished as the Moors; took a lot longer than with the French, until the early 15th century as a matter of fact. It was a much more interesting campaign too, once the Christians got their act together and fought back at me. Got a bit tedious towards the end, and the Timurids could have caused a problem if the strategic AI hadn't been so completely boneheaded.
I patched the game, and am thinking of starting another campaign as a faction that'll have to face the Mongols and the Timurids head-on. That would be either the Russians, Poles, Hungarians, Byzantines, or Turks. I gave the Russians a quick whirl but got turned off by the carelessness of the implementation -- the unit icons look frankly bad, there are typos galore (e.g. Ysevolod instead of Vsevolod), and, being a Finn, I was somewhat amused/embarrassed to see Helsinki on the map, considering that it was only founded in 1550 and was known only as Helsingfors for another 300 years or so.
I guess I've been a bit spoiled by Rome: Total Realism. It hurt my suspension of disbelief to be able to recruit camel gunners in Toulouse, and Tuareg spearmen in Constantinople, never mind that firearm-equipped cavalry is available long before firearm-equipped infantry, and such. Here's to hoping there'll be a M2TR mod as well, one of these years. The game deserves it.
