Just picked Shin Megami Tensei IV up during my lunch break, but didn't have time to unbox it and dig through the manual--if there is one--but I noticed that the back of the box mentions StreetPassing. Anyone know the details? Can you swap demons or gain extra Macca?

Mmm, lovely. Another addition to the worthless features of games I don't get to benefit from. Waiting on my copy to come UPS but it's possibly something like Strange Journey's demon code swapping. Not really much else they could do.

I forget all the details, but it's definitely a lot more in-depth than what Soul Hackers did. You basically assign a demon (or possibly even a team of demons) to your character for street passing. The only result of this that I can remember is that it's possible for your demon to come back and evolve into a completely different demon, although I know there's more.

There's also a kind of hidden feature where if you streetpass someone with Etrian Odyssey 4 or Soul Hackers you get free app points to unlock more features for the Gauntlet. (I had originally heard you just needed save data, which would have been way better. Alas.)

Zeik's got it. You make this little card for yourself, either white (for just showing off) or black (for fusion with the demon of other people you pass), and assign one of your demons to it. The demon you assign can't be used in battle with it turned on.

The main benefit from using the black card is that it offers a high chance of fusion accidents, which will be good in this case as there are a number of accident-only demons who are quite useful. So, when you make your card, just don't put one of your most valuable demons on it.

In addition to the app points (which I only ever got once), the more tags you get means that your demons can give you some items upon their return, which can be healing items or even weapons.

It's a much, much better feature than Soul Hackers', though I'm curious just how well it'll work in a place that isn't Japan.

@eirikr: I recall hearing recently that Nintendo was going to update their street pass mode so you didn't necessarily have to street pass directly with someone. I don't know if that's still happening, but I it would definitely help for games like this.

@zeik: Yeah, if that turns out to be the case, then that'll be even better than actual person-to-person tags, though I haven't heard word exactly how it would be implemented. Hopefully it hits soon (and I also hope I can tag my US copy with my Japanese one)!

I wonder if I'll ever even get far enough to unlock the StreetPassing stuff. I have now died FOUR times on the tutorial boss fight in Naraku. Oh man...
