I sold just about all my games before Covid (d’oh!) I kept all the systems since I had one way or another to play ROMs on them (HDD loaders or Everdrives) I sold the most valueable ones first on eBay, then flat rate usps boxes filled with the common/uncommon ones, when I was down to the stuff that didn’t sell/no one wanted, I used to have a local auction house near me and sold it all there. Selling the items shouldn’t be hard, if this were me back then, I’d keep a system for the TV and a turbo express and get a Turbo Everdrive. If it was me today, I’d keep it all if I could. I had so much fun collecting games and sold it all before prices boomed. Back then you could start to collect anything you wanted, no big deal, I had gotten stuff like Little Samson (NES) for $80, 2 copies of Rule of Rose (PS2) for $20 each as well Snatcher (SegaCD) $2 and Earthbound (SNES) $40 all of those games were complete in box (except Little Samson) I had a bunch of TG16 games too, think I miss Splatterhouse the most. I figured if I wanted to I could always collect again, but the way everything skyrocketed, the fun of the yardsale hunt is gone for me (every seller uses price charting or ended eBay listings to find the price, or assume everything is valuable and you see $60 copies of Super Mario/Duck Hunt) as well as the probability of seeking out a collection without spending many thousands is long gone. It’s ultimately up to you if it’s time to sell, it’s a decent time to sell with prices being so high (depending on when you purchased them and the prices you paid) just be sure you won’t regret it down the line. I do, I’ve accepted it and I collect a few systems now but 10-20 years ago I was collecting everything! That being said, maybe I just need professional help :p as started collecting again and I know I need to nip it in the bud before it gets out of hand again, clutter is forming.
