Even though there are more to announce, this slide contains many titles which fully utilize the GamePad. In addition to Mr. Miyamoto’s GamePad Utilization Project, UGC (User-Generated Content), where players can enjoy other players’ creations, is possible in titles such as "Mario Maker" (temp.). Gameplay that utilizes the GamePad possesses a large amount of potential, and it can further expand the way parents and children have fun together.
I think some games that will be announced are Paper Mario, Metroid, SNES Remix, Animal Crossing and some kind of Mario spinoff.
