>>27266513As far as I'm concerned it's a retcon, the universe was actually complete with the first two games. They removed the reference the South America in it's Pokedex entry, stopped talking about it as the ancestor and instead went for some mythology shit in Gen4.
Back in Gen1&2 though, everything had already been tied up, Pokemon were descended from Mew, it was the big thing back around the time of the first movie.
There weren't even any other Pokemon Leagues prior to Gen3 either when they made them region exclusive. Remember your rival says "I am the most powerful Pokemon trainer in the WORLD" and Gen2 used the same league.
I still believe the original idea was that Pokemon were born of genetic mutations or something, the game taking place in the near future. Nowadays they don't reference the real world. Making a brand new mythology and taking it into a fantasy world is a retcon by most definitions.
