From the preview:
"The Mystery Dungeon series has hit our shores before, in the form of the Pokemon Rescue Squad games. While most of the games revolve around licensed characters from other series, Mystery Dungeon: Shiren the Wanderer was the first to feature original characters. Originally a SNES title, Sega is bringing Shiren to our shores later this year. From our exclusive hands-on time, we're excited to have this classic dungeon crawler available on the go -- with the caveat that all we're expecting from it is classic dungeon crawling."
