I'm fairly certain the people at Game Freak who model and animate aren't the same who handle the typing mechanics, let alone programming it into the game. These kind of jobs get sent to teams . The "they've got so much on their plate" argument makes no sense to me. It's not like this is 10 guys sitting in a crammed room with 3 computers between them rushing to complete this game on time.
Isn't Game Freak four people in Celadon City?
