Hehehe Always fun to worry a Age's Writer.
In the interest of fair play the final version of my Shell's rooftop Garden Terrain will probably have a significantly lower poly-count then it currently does. I like doing my height map sketch's in planetary scale.
Actually the memory needed for Ahra Pahts has always been something of a concern ever since I first saw the Age. I assume once the shells start filling up it will become much much worse. Out of curiosity if the memory requirements get really bad will you fracture the city by district into separate Age files stitched together by the hub?
