Junichi Masuda has worked on every mainline Pokemon game to date, but Pokemon: Let's Go, Pikachu and Eevee! will possibly be the last Pokemon RPG he directs.

Masuda dropped the news in an interview for Pokemon's official website. In the interview, Masuda spoke about how he enjoyed working on a Pokemon game for the Nintendo Switch and brainstorming how to connect that game with Pokemon Go. He also explained why he's likely stepping away from directing the series.

"I was the one who worked on the base game concept document for Pokemon Go, and even in that original concept, I had the idea of introducing new Pokemon through the mobile game," said Masuda. "I wanted to realize that goal by creating games that could connect with Pokemon Go and feel somewhat similar to it without feeling like we were copying it. Given my involvement in Pokemon Go's development, I felt that I was probably the best person to direct these games.

"It was also interesting to work with Nintendo Switch. There's a lot of technology packed into the hardware that we were all trying to discover at Game Freak. For example, developing the Poke Ball Plus and working with Bluetooth to facilitate the connection with Pokemon Go were both very interesting things that I had a chance to work on as the director this time.

"But at the same time, it's important to have the younger generation at Game Freak take over the development of Pokemon as a series. I do believe this will probably be, in terms of the main Pokemon RPGs, the last time that I work as the director."

Masuda first began working on the series by serving as the composer for the inaugural games, 1998's Pokemon Red and Blue, before shifting into theassistant director role with 2000's Pokemon Gold and Silver and director role on Ruby and Sapphire

IGN interviewed Masuda about Pokemon Let's Go earlier this month, in which he said he wanted today's kids to "experience something similar to what kids 20 years ago also played."

Nintendo will release Pokemon Let's Go for Switch on Nov. 16. Let's Go works without Switch's motion controls and features a mythical new species of Pokemon.
