What's the GeoRealism have to do with multimaps? I thought multimaps were just getting units from one map to another. No matter what the map script we are using.
Because if multimaps are not possible, I would like to move on to plan B, which would be the map with subdivisions on the same map. We know that's possible, but its not as cool as multimaps. But I would use it if multimaps are never coming, since we need something for the "Cosmos" part of the mod.
Multiple Maps are most certainly possible, it is just a matter of none of us really wanting to work on them. But now that we have Viewports there isn't any software reason so far as I know that we can't have Multi-Maps.
