>Why did you decide to have 151 Pokémon?
>Sugimori: At first, the game was more RPG-like. It was only in the middle of development that the goal of the game became completing your Pokédex. That’s when memory capacity and deciding on a good number of characters became an issue. We actually wanted to have more. We designed around 1.5 times more characters we actually used.
>Why did the game change from an RPG to one where your goal was to complete your Pokédex?
>Sugimori: When we were writing the text for the Pokédex, we started talking about how fun it was to collect Pokémon. We hadn’t wanted to do a fantasy RPG from the start. We felt a story about a boy travelling to fill up his Pokédex was more appropriate for modern times than a tale of a hero battling an evil villain.
