so with 'Spotpass Mii's' - How do we receive them ??
Do we have to play a [3DS] game online with 'friends' to get them (e.g mario kart),
Have FC in our list & get them if/when they switch on their 3DS the same time as you,
or
Will we just receive a random Mii when walking around & passing any [unlocked] WiFi routers ??
I think people are still trying to figure this out.
Hopefully when those details are confirmed he'll just clarify in the first post, or link to the info.
I've not received the Miis of my distant 3DS friends so far (even when we were online simultaneously), but I dont have any multiplayer games yet to test that first idea of yours. Even though I've definitely enabled Spotpass in Mii Plaza on both of my 3DS units, I'm still only seeing streetpass Miis. I'm sure by the time I notice something different happening, others will have already figured it out and commented about it though.
