Here's a scary thought:
It seems like everyone is getting at least a handful of Mii's in the past--- what, 10 days?-- that the 3DS has been out. It seems nifty, we get pleasantly surprised when we see that green light.
And there's, what--- maybe 1 million, maybe a bit more-- 3DS's out in the wild right now.
What's it going to be like in a year, or 2, or 3, when the 3DS has sold more than 10 or 20 million units. It seems cute if we get 1 or 2 streetpasses a day, or every other day, but if that rate stays consistent or rises (as it would, as the population of 3DS's on the street grows and grows)....
Boom! Mii Plaza overpopulation, folks. That's right.
You've got 5, or 10, or maybe 20 Mii's in your Mii plaza right now. What happens when you get (and you eventually will) 100, 200, or even 300 Miis? Do they all display on one screen? Do you have to scroll through these hordes and hordes of Miis? Does the 3DS erase old Miis? Or do they just linger around, staring at you, craving your attention?
Okay, so this is half-serious. But now to be completely serious, does anyone know what will happen as the accumulation of streetpasses and Miis increases? Is there a limit, or does it just keep going and going? I know this doesn't seem like an issue now, but this may be, a few years down the line.
