I was about to suggest this one too! I just finished the second book and am really enjoying the series so far.
Went to a flea market and a few retro stores I hadn't been to before up in Michigan and walked away with a few solid new games to add to my collection! I paid $100 for Lone Ranger+Best of the Best Karate and $40 for Lagrange Point. Not the crazy deals I used to see, but still pretty happy!
Btw, I'm just treating Lemmy like I used to treat /r/gamecollecting. Let me know if posting "finds" here is annoying.
I can't say I've ever found a gem when I wasn't looking for games at all, but I have found some when I wasn't expecting anything exciting.
Probably 10 years ago, I was in a kind've sketchy store in a flea market near Baltimore and found a booth piled up with old electronics and games. Was not a very nice looking place and had bootleg GBA games in a glass display case and a table of more modern games up front. I dug around in the back of the store and in one pile of wires and controllers spotted a loose copy of Dragon Warrior IV for the NES! The lady manning the booth didn't know/care what it was and sold it to me for $1. One of my favorite finds!
I also later found a boxed copy of FFV GBA (not bootleg) and a CIB Paper Mario Thousand Year Door there. Not sure what I paid for those (probably $10 a piece or something).
Just parroting stuff I heard at black hat, but aside from all the above don't we first need to have millions of logical qubits? I believe the numbers people advertise now are just physical qubits.
