Well, I do have a (turn based) strategy game verse myself, and from all of my experience, I can comfortably tell you... I have no idea. I mean seriously, it's just a pick 'n pray situation. Obviously if it's about destroying a building/city, you use the building/city itself, and so on for anything else, but other than that, I dunno. So, I think your assumption is correct there, if it's a large city you treat it as a large city.
