[SCENERY] MegaSceneryEarth State vs City vs National Park ground textures

Hi again, everyone!

Thanks again for the wonderful help last time. This time I have a quick question regarding the differences between state, city, and park ground textures. The product descriptions list a 50 cm per pixel resolution throughout all levels, but not many more technical details than that. The product details do say, however, that the two versions can co-exist, just that a user may place the more localized version higher in the scenery load order.

Apologies if I am overthinking the 50cm thing, but can someone please share what is the added benefit from having these more localized editions, or is there really that much more detail? Say, if I already have the State of Colorado, why should I get Denver and the Rocky Mountain products, too?

Thanks again for bearing with me!
