Pokemon Forums According to Nintendo

Never played a demo so I wouldn't know but my thinking is that it won't transfer. Doesn't take that long to reach the first Dungeon though. If you know what your doing, figure ~10 minutes but if you go slow and explore and factoring in first time delay, maybe 30 minutes or so.

Any game with Zelda as the main character is a win in my book. I've played traditional Zelda and the Dungeons are just like Dungeons in A Link to the Past or Links Awakening. Whether they're as difficult is another question.
