I haven't had a lot of luck with StreetPass encounters. Shortly after the aforementioned post, I met two other Miis in the form of Gamessa and Clif, making for a total of three people I've come across since the launch of the 3DS in March. My experience with this feature has been disappointing, especially since receiving duplicate puzzle pieces in Puzzle Swap is common when purchased with Play Coins, as opposed to being guaranteed a new piece when encountering a fellow player. Having never been to a convention where it's common for people to pack their 3DS, I was excited to see what would happen when I visited the Whiskey Media office on June 24th. Arriving back at my hotel later that night, I had completely forgotten that my 3DS was still on and in my pocket. I excitedly took it out and booted up StreetPass Mii Plaza to be greeted with this:
As you can see from the second pic, I totally had the inside scoop on Matt Kessler's first review.
I then loaded up Puzzle Swap to reap my rewards.
Though I've technically finished Find Mii, I still have a few more hats to collect. Here's what the guys look like when pissed off at ghosts.
I also had the StreetPass functionality for Super Street Fighter IV turned on, and was surprised when I saw that Jeff was one of my opponents since I didn't encounter his Mii.
And those are probably the last StreetPass encounters I'm going to have for a very long time.
Oh, and if there was still any doubt as to the identity of the man in the following photo (from this thread), I think Ryan's Mii is enough evidence to lay this mystery to rest:
