I always thought it would be cool if a game could generate a monster by taking a sample of your DNA, like a piece of hair or some blood.
So, what I gather from reading and watching the trailer is that you walk around and some sort of magnetic device in the DS card can measure magnetic fields. These fields readings then become the stats for your monsters. Sonic clues let you know when you're near really good magnetic fields so you can build better monsters.
The kids in the trailer seem to have mapped out their local area to know where to stand for the best magnetic fields to build better monsters.
Nothing about barcodes or GPS.
Erm... Flash Memory doesn't work with magnets. You're thinking of Hard Disks or Floppys.Magnet + Flashcart = Data erasure.
It would be pretty damn cool, especially seeing everyones monster could be unique. Trading would be endless, you'll never collect every monster possible! I'd be wanting to make monsters from my cat, dog and hamster. You can imagine a thread here that says "Show Your Pet In DND Monster Form!!111!!".I always thought it would be cool if a game could generate a monster by taking a sample of your DNA, like a piece of hair or some blood.
Just as a side note. I was able to get newer more powerful monsters when scanning while I was using my microwave. >.>;;; go figure.
