Wow, the 3DS demo is awful. The Vita version basically lets you play the entire opening of the game, including tutorials, whereas the 3DS game gives you a couple of minutes of the hub section, then sets you loose in a dungeon. If I hadn't played the Vita version I'd have had no idea what the hell I was doing. You get three floors to explore then the demo ends. The Vita version looks better too, with much sharper models, and the 3DS version seeming to criminally underuse its 3D advantage.
