The first time I was ever scammed was buying a large lot of MVS games off Craigslist when I was around 16 (2009). I traded a bunch of CPS1/2 stuff for them. Ended up making about $100 back, selling them off as counterfeits for what was supposed to be about $1000-1500 trade from some asshole in Florida. It was only then I realized how professional bootlegs could be, before opening games was even standard operations as it is nowadays. You had nothing to compare them to like the databases we have now.
