Obviously, there's been some criticism about not including all of the legacy Pokémon in the game. How much of that is related to the challenges of this already being a huge team and the staffing resources it would take, and how much was it a creative decision that you knew you'd have to get to eventually?
Masuda: I think it's fair to say that both are involved. I mean, in any design situation, resources and time are always a constraint on what you can do in a project. But at the same time from a creative perspective, it's part of
a discussion we've had at Game Freak with Nintendo and The Pokémon Company, and we came to the decision that, at some point, we need to be able to prioritize new gameplay ideas. We need to be able to find a way to balance the right number of Pokémon and also still introduce new ways for players to enjoy the game, new gameplay ideas to keep the series fresh and enjoyable far into the future.
