[quote name='trent82']how close do you need to be to another 3ds for the street pass stuff to happen? where i live, i could easily see myself owning this system for years and never encountering another 3ds. it seems like a mostly pointless feature for people who live in small towns.
i hope they patch in other ways to earn play coins, because at 10 per day, find mii and puzzle swap will take forever to progress through. today i spent all 10 coins on 5 puzzle pieces, and 2 of those 5 were repeats. that is just stupid.[/QUOTE]
I believe that would be 100 feet.
In another videogaming forum, someone said there's a workaround to that limit by changing the system date (to an older date, I'd assume). It'll reset the step count but the # of (unspent) coins will remain intact...so you can earn more coins a day. Lather, rinse, repeat. I haven't tried that trick yet, though.
