Yeah, this is totally doable. But I think I'll just let someone else do the rest of the map, at least for now.Sounds cool
Maybe you should include the Arabian desert in this too, since even when Rome spawns it is an un-productive box of sand. In Babylonian days, there were more plains, but desertification has since taken place.
Or maybe you could even make Spain have more grasslands, but they will turn to plains as time goes on.
