Bonding over Pokemon

This isn't necessarily one particular stories, but I guess kind of a series of them. Pokemon was a thing that brought Jordan, me, and Bre together for several years.
When Pokemon first came out (the trading card game, gameboy games, and the TV show), it was pretty much immediately huge. All the kids at school were into it. All the kids at the apartments we lived in at the time were into it. It wasn't surprising and that Jordan and I got into it, too.
But we weren't able to afford to as many cards as everyone else, and a gameboy was out of the question for a bit, although we ended up getting one later. So in the beginning, what we used to do is sneak out at night. There used to be a gathering of kids in the nearby playground at night that would trade cards in the dark, almost like it was some kind of black market. 
We didn't have anything to trade, but many of the other kids would give us cards they had two of, or cards that weren't very valuable. Jordan and I amassed a small collection together that way. Eventually, we had our own binders of Pokemon cards. 
When we got a gameboy, Jordan was the first one to play Red and Blue version. I didn't really get into those, but when I did try playing them, he taught me that cheat with MissingNo. The one where you get 99 of an item in your bag if you find that creepy, glitchy Pokemon off Cinnabar Island. He insisted that I must always save my game every time I played.
I got more into it when Gold, Silver, and Crystal came out. It was at that time that Jordan started to become bored with it. He said he would pass on his card collection to me or Bre, and let it hang over our heads for a few days like we'd have to compete for it. In the end, he decided to give it to her because her own collection wasn't as big as mine, and she needed cards more than I did to round it out. 
Unlike Jordan, I never really grew out of it. I still actively play the new Pokemon games to this day. I wonder what he would think if he knew how valuable some of those old cards we used to collect are now?
