Yeah. The mentionings of the real world in the older games are, in TVTropes terms, Early Installment Weirdness.
I honestly wonder how much of the lore was made while they were making the games. Maybe they didn't expect there
to be a lore, or perhaps the use of real world references were just placeholders they forgot to replace. They occasionally still use older PokéDex entries, so either it's just laziness or the hidden lore is that the Pokémon world is post-apocalyptic (pretty much was the backstory to Kalos, after all). And apparently Pokémon come from space, so you
could say Pokémon literally being an invasive species is what replaced all the real-world animals and humans learned to coexist with them because mankind is resilient.
Really is too bad we never got more of it, I think it'd make for some interesting world-building.
Meanwhile I had a small talk with a brother a day or two ago when he asked what region Ryme City is in, and I answered that it's not known, but given the cameo of Ash's Pikachu in the game that it
may be in the anime-verse for all we know. For a spin-off game it stands on its own very well otherwise, but that and the "It's not French" line everyone's been freaking out over is bringing up questions about geography.
