I live in a super tiny town on the edge of nowhere, so I only met like six people, who all regularly streetpassed with each other. So I set my router up with fakepass or whatever it was called, the software that let me streetpass with people all over the world, and that was huge fun. Then they set up some kind of thing where every Mcdonalds in NA was streetpass linked or something, so I didn't have to do the router thing anymore, and I started making regular trips to the park beside McDonalds, because their wifi just barely reached and I'd get streetpasses.
I bought the Plaza DLC, whatever it was called, and I played every game for hours. It was just so fun to see that there were other people doing the same thing as me. It made everything feel a bit like an MMO. I wish it'd come back for the Switch 2.
Even though I live in a fairly large city, I'm not ever really in a situation where I'm likely to pass a lot of other people who also brought the console with Street Pass turned on.
As such, I used the router hack to fake it. That was awesome, but I mostly enjoyed the free stuff I was getting, since it really had nothing to do with other people. That basically means the game would have been better off with just giving out free stuff randomly instead.
Of all the games I play with "Street Pass", none of them really made sense of that feature. It was either required to play the game (which was lame) or it was free stuff for a game that should be perfectly fine without it.
I definitely wouldn't call it exciting, but it was novel and somewhat cool... At least as an idea.
Because it’s peer-to-peer, there’s no server to take down; it still works if you can find DS owners. These days, it’s mostly cons like PAX, and even then, not like it was in the heyday.
