>>50558879That faint glimpse of what they were planning is exactly what he was referring to. This idea that Kanto only appeared by the grace of Iwata is not entirely accurate. Game Freak very much wanted to have multiple regions in Pokemon 2. Moreover, when you say that Kanto was added in a few days before release, you're implying one of two things. One: that they went back and adjusted the levels of every Trainer in the game to accommodate something they scraped together at the end of development. Or Two: that Johto was really going to end with the majority of your team coasting around level 40~50, assuming you decided to grind for the Elite 4, because you definitely don't get there around those levels.
That means Johto's terrible level curve was either a direct result of adding in a rushed Kanto, or it was intended from the start.
