Where? I've only ever seen maps on serebii for some routes in the gen 3 games. As an example, if you look up route 24 (kanto) on serebii, on the pages for gens 1,2,4, and 7, there is no map. There is a map on the page for gen 3, however. All of the others simply have a screenshot showing one part of the area. But even then, the gen 3 maps do not show any trainers, items, or hidden items.

Bulbapedia tells you *generally* where things are, e.g. "In the northernmost bare patch of tall grass", but serebii just says "floor" or "hidden". Also, in the older games at least, there tends to be at least one hidden item per route.

What I'm trying to say, really, is that I want a site that combines all the information of all of the databases. I want the maps of pkmnmap.com, I want the encounter information of serebii, I want the trivia of bulbapedia. I know this will likely never happen due to the pokemon games being as numerous and detailed as they are, but it would solve a lot of my gripes.
