Is that what RTR and SPQR have done? Are the 2-6 versions really more tweaked and stable and refined versions, or are they lots of new things, new units, new faction work, etc.? I honestly don't know, but I thought they have kept adding new faction units, new versions of vanilla units, etc. Is the change from RTR 6 to 7 just a refining or a totally new map, twice as many new factions, and things like that?
