not sure if it's realized or not but you can't set a building as a pre-req for the actual construction of a unit (assuming that it's not autoproduced). it's resources only (and certain civs).
if the brits get colonial infantry units then i would imagine that the other colonial civs should get them too. no? only fair imho of course, if you want to tease out some differences in the colonial unit lines then that is fair (ie higher costs for crappier colonial units, differentiation in a/d values, hp allotments etc). granted, having colonial units like this...would require isolation of resources which takes some arranging in the biq file to assure that the phantom resource bug does not appear.
Yes I do realize that we can't use a building as a pre-req and was in fact thinking exactly as you saaid to use it to auto produce units. Particularly with the french as their colonies consist of single towns that are separated/dispersed in most cases. this is also true with most of the other colonies with the exception of the brits. The question here is how do auto-produce more than one type of unit. In other words is there a way to get a build to auto produce a selection of say 2 or 3 different units?
The bigger problem is how do prevent colonies from producing regular units?
There was an ancient roman scenario, can't remember which one right now, that used a region label as a resource (Italy, Carthage, gaul, etc.) perhaps we could do something like that to control the product of homeland/ regular units.
Could you elaborate a bit on the "phantom" resource. I am not familiar with that.
