Thanks, Juzza - right now I'm feeling around for what is possible, as I did not know about the unit DESCRIPTION limit! For recolored units, I will definitely want a musketeer, a female Elven archer, something to stand in for Julia, possibly some Dwarven units, but most of the other races I think are around. Then there's machines, which as you say should be around. But THANKS for your offer! I will definitely take you up on it once I know what I need (if you want to suggest anything, go ahead)!
Just to clarify on the descriptions: there suppose that you try to load two separate mods each of which have 150 descriptions. Will this overwrite each-other?
Anyhow, yes, I was intending on making flagships and transport ships not only sailing but also give them the ability to allow troops under their "command" to enter the sea. It doesn't matter if the AI wants to make Prophets out of them; after all, if they are the commanders that go into the sea, then ordinary commanders can't go, so there have to be applicable prophets.
