@ Xeofox,
I'm not quite sure about your reservations. As you know most gis datasource provide their data in latitude-longitude format. That includes elevation, coastlines, rivers, places and the available dataset on ancient places, roadsystems and so on. Any self respecting GIS will allow you to define your projection according to your needs. Qgis definitely supports the kind of projection used by Google Earth or something very much like it. The GIS I use certainly does. So, I do not see why opting for one projection over another would affect the availability of geographical data? The question at hand is, knowing we can choose any projection system we want, which suits your goals best? The orthogonal and (other) perspective projections have the advantage that the area the map is centered on has the highest resolution and this can be used to compress the periphery where in this case is either "dead space" like Siberia or the Sahara, or a series of regions that currently are rather larger than the others.
Btw, my background is physical geograpy, so my focus in GIS tends to be primarily on the physical environment and on rasterized data. However, I'd love to work on a map that faithfully incorporates historical geography as much as possible. For RTR VII I managed the accurate placing of settlements allright, but there are a couple of aspects that I never got quite around to doing well, mainly concerning the infrastructure and land use.
