Okay. Since my last idea had some holes in it, I came up with a better one. The trailer opens with the two protagonists reading a book. The camera zooms in on the book to reveal the game title then the camera shows the inside of the book. It shows us a few pages with the text revealing the game's plot. Afterwards, it shows the protagonists getting sucked into the book where it then shows them collecting Pagies and performing some of their moves to fight enemies and get to other areas containing Pagies while the page text advertises the game. At the end of the trailer, the book closes and we see the front cover, which reveals the name of the game.
What do you think of this one?
