Demons are pretty cool, right? Well how about a demon that grows as you meet other folk with the same game? Yep, that's Nintendo's Streetpass software for you, but this seems like a pretty neat application of the technology nonetheless. 

Devil Summoner: Soul Hackers will contain over 30 new monsters that the Sega Saturn original never had, including Nemecchi, who will grow stronger as you collect more and more street passes. Nemecchi will also change appearance the more you do this, which will serve as a good indicator of how the fella is doing.

Just imagine what it'll be like when the monster-collection games use Streetpass in better ways! Trades, battles, evolutions... there's so much potential! Any reason for Nintendo to have you keep your 3DS in your pocket is a bonus, too.
