Around 2003 I sold off my SNES with a bunch of games. Final fantasy 3, Chrono Trigger, Contra 3, DKC trilogy, Mario world/Kart/ Yoshis Island, Super Metriod and Link to the Past, and lots of other games like that. I was deep into the 6th gen and at the time it seemed like I was over the 8/16 bit era. Going back to the 80s I was always prone to sell off the older gen stuff to fund the new. But this time was different.
Literally the next day, I had a gut-wrenching 'sellers remorse' punch in the pit of her stomach. I even went as far as contacting the buyer( it was local) and offering them more than they paid. Nope, they were holding onto it. So I went onto Amazon and bought a system, then went on a thrift store/garage/ yard sale goose chase tracking down SNES games. This was at a point when they were as commonly found laying unloved at the bottom of a storage bin as something like Wii/Ps2/xbox games were a few years ago. People were giving them away or selling them for relative pennies.
What's happened in recent years was a push to expand my horizons to other systems I once owned: Saturn, N64, Dreamcast, Genesis, Gamecube. But its led to some unfocus, of 'this game is $2 so why not' purchases which have padded out the collection, but I realize that alot of these games were bought with only casual intent to play 'eventually' and that ship has sailed in many cases. I could do with a good curating and refocusing of what I actually want to play and what merits ownership beyond simple possession for possession sake. I don't have a huge unmanageable collection but some games just don't need to be in it anymore.
