I’ll go first. About 20 years ago I sold my collection from my childhood for $800. I had the nes, snes, n64, GameCube, ps1, and Dreamcast consoles plus a ton of games. I have no idea what it’s worth these days, but I had complete mint in box copies of ff3, Chrono trigger, ff2, earthbound, Mario rpg, castlevania Dracula x, ff7 black label, and hundreds more games across all the consoles. I regret it to this day and don’t even want to know how much it is worth now, or potentially down the road.
