Thanks for your forgiveness. Now back to decisions decisions decisions. I already typed my opinions already in a previous post. Paraphrased, I said go for Mag, but logistically it wouldn't make too much sense to send over an entire army to the other continent due to us not having secured our own yet. However, if the Aztecs are becoming the juggernaut we all will fear, and if we can successfully cripple another civ (English) to the point they are a non-threat, when Mag comes around in 11-12 turns, then let's send over that army with the pillaging cav.
But now as I think about this even more, I'm starting to recall your observation of ironclads. Meaning the AIs are already up Steam and one tech closer to destroyers. Even if the defense of a galleon is 3, we will be risking an entire army in open waters. Sigh...
I'm not really helping out by giving my vote, but only laying out the facts. Not sending an army at all will severely kill us down the line by letting the Aztecs run unchecked. Sending one over and we will need to survive approximately 5-8 turns of Ironclad attacks before it can land.
One possible alternative is to wait for us to have steam power and our own set of ironclads. With proper escort, we can definitely send over that army, certainly with much less apprehension than before.
I never thought I would be saying this since it would have been bad luck to be so portentous, but since the AI is now in the IA and we don't look like we're near death, let's hope the AI will go communistic on us

They already have nationalism, so let's all pray for that.
One question barbslinger, why navigation? IIRC, NAV only provides the ability to build Magellan's and explorers. It doesn't provide sea or ocean travel (that's Astro and Mag respectively), so aside from explorers, I don't see why we need Nav at all.

I know the explorer's pillaging capailities, so maybe you were thinking of sending over explorers with the cav army?
