Yeah, I mentioned to pay attention to scale in each of the posts. I guess the fourth time is the charm. :-)
Orders of magnitude are important.
One or two orders of magnitude are usually normal in games.
Any time you see four or more orders of magnitude out of scale, it is so far distant that it doesn't even matter.
When you're working on meter scale, any power of ten (e0xx) more than +2 or -2 (or more) means something is likely broken.
Going bigger, e+2 and you're talking about the distance of sports arenas; still possible in games but less common. e+3 is kilometers where you're normally looking at different levels or zones and normally not used in games. e+4 and you're talking the scale of cities. e+6 and you're talking full planet diameter.
Going smaller, e-2 and you're talking centimeters which are about the limit downward. e-3 is millimeters, the scale of a fingernail width and usually too small for games. When you had e-5 you're on the scale of the width of a hair, e-10 you're on the scale of a single atom.
