one single runtime. varies from 7 to 11 gig. one backup, updated monthly (more or less). no direct installation of whatever. check all the files, geometries, textures, rename them reasonably and set your own paths. there is no merchants name in my runtime (well, apart from "runtime!DAZ", that is). write your own scripts for everything and make your own pngs. test everything right after pasting it into your runtime. too much effort? it is worth it! ive tried it with multiple runtimes......huh! now thats complicated! and too much wasted HD-space.
