I just started my first game as Montezuma and I'm really not that impressed. 1. The odds of capturing an enemy unit seem pretty low. I've waged three "recruitment"-wars against CS', killed maybe 14 or 16 of their units and got three builders out of the whole thing. In the last war I killed four or five CS units and didn't get a single worker. Yes: The three guys I did get were a nice boost to my early district-construction/tile improvement efforts, but it hardly justified the overall hammers I had to put into producing my three or four Eagles (plus an Archer or two). 2. The Eagles are becoming useless pretty fast. I made the mistake of starting my last war without thinking too much (silly me) and didn't pay attention to the fact that I had arrived in the Classical Period. Result: Nearly all other civs started hating on me (Gandhi even said something like "perhaps you should be removed from power", yikes.. please don't nuke me, dude! ). Plus of course once you hit Iron Working you're losing the Eagle's ability altogether anyway. I was thinking about keeping them around a bit longer, but then I ran into a barb camp that spawned a swordsman per turn for four or five turns in a row and quickly changed my mind.. Perhaps if their ability was a unique promotion and carried over once you upgrade? I don't see why it shouldn't since, in the case of the Aztecs, capturing slaves could be seen as a cultural thing and not bound to a specific type of unit. Keep the ability around until you hit a certain civic (like The Enlightenment) and *then* make it obsolete and strip it from any unit that has it. S.
