StreetPass was a super cool feature. I used to take my 3DS on the subway with me and see how many new Miis I would get. Too bad there is no equally cool replacement for the Switch.
Street pass was the shit. I remember taking my DS to school to get as many hits as possible. Now with the age of portable gaming handhelds it’s kinda crazy nobody has created some kind of open street pass service.
They didn't actively remove it, they just didn't reimplement it. Streetpass seems like a lot of work to implement, and with the move away from miis it probably would have needed a complete overhaul.
