>>3968760615 years ago I didn't know the regions were based on Japanese prefectures. I thought K*nto being named after the real-life Kantō region was just the result of an uncreative writing staff. I was sure that we'd get a game where not everything would be available, since that was essentially Gen 3 anyhow. If you can't catch it in-game it may as well not be available at all.
Honestly I'm surprised the series didn't end with Arceus.
