While there's a lot of useful places there, Rustboro really isn't one of the nicer cities in the Pokémon series. It is a fairly large one though, so I added some NPCs walking around to try and make it seem at least a bit busy. Does it work? Sorta, though to give a "big city" feeling it could probably use at least a few more. Then again, this is Pokémon we're talking about. Prior to Black/White, even the biggest cities only have a handful of NPCs. Anyway, there aren't many strips when I actually put in "extras" so to speak. While they can add to the atmosphere, adding them takes time and can make the rather small panels pretty crowded.
