Hey, thanks.
That file also explains exactly how the aid promotion formula works. I was wondering about that.
I saw that there is a big gap in the recon units and there are no modern cavalry units. I remember a civ3 mod that had renaissance and modern recon units. The medieval recon units would be horse based light units and the modern recon units would be units like a motorcycle unit and a humvee. The helicopters could then be the modern cavalry units.
Since recon units have a lower combat strength, maybe their aid promotion should work a bit different so that you don't need a mass of recon units to get the recon aid promotion.
Another question. If I change these things about the crowded promotion will it apply to the game I'm playing at the moment or do I have to start a new one?
