What type of game will be best for a new Kid Icarus game.

[HappySqurriel]

Hybrid platformer/adventure game ...

If you take Zelda and add some of the platforming elements from Mario, or take Mario and add some of the combat/adventure elements of Zelda, you end with a game where the movement and combat elements of a character like Pit could be used to create something really enjoyable.

Edit: To a certain extent the platforming elements would play something like Banjo-Kazooie, but if it was using an art style and them more like SotC or Zelda: Twilight Princess you could create a new classic.
