Square Enix president Yoichi Wada has admitted in a speech that over-use of an IP is "not good."
He made his remarks during a keynote at the Montreal Games Summit.
"Too much IP use is not good," said Wada.
"Having memorable characters and back story is crucial to having a powerful IP."
Wada also stressed though how the Final Fantasy IP hasn't become tired yet.
"As long as there is a world with enough content and story, players will feel comfortable being in the same world for extended periods of time."
