Coming to terms with selling my Video Game Collection

I had a period of my life where I was really into the idea of collecting games for a wide variety of systems and keeping them for when I would have time to play them.

I amassed a pretty sizeable collection (at one point my games, complete in box, totaled around $20,000 dollars). I had hundreds of games that were worth more than $50 dollars individually from systems of every category, including 3DO, including CD-i.

I sold a good chunk of them and made around $4,000 dollars after fees, etc. that I used to help pay for my house.

Now that I'm in my own house and have some new debts I've never had before, I have finally started to realize that my game collection has not been touched. I have at least 100 games that could sell for over $7,000 dollars very quickly if I managed the selling process correctly. This would wipe out my debts and then some.

Not only that, but I have several consoles I do not play. PSOne, Xbox 360 Elite, TurboGrafx-16, Super Nintendo, Sega Genesis Model 1 (HD Graphics non TMSS version) with recapped Sega CD Model 2, etc.

Most of these systems I have not touched in years, and when I do, I play through maybe half a game and put the system back in storage. I keep telling myself I will play the games eventually, but, I'm starting to come to the realization that I'm probably never going to sit down and spend hours of my life on a single game on a single system in my living room anymore, and that all the games I bought are just being archived.

For no reason.

I have attachment to some of them, but what does that attachment actually mean? Why do I have an attachment to a piece of plastic? There is value in physical media, true, but I have all of these games as roms saved to multiple backups.

It's far more convenient for me to play one of those, and even then, I don't. I've played through a total of 15 Sega Genesis games, yet I collected over 80. It would take me years to play the remaining games, JUST for that system alone. And I mean really enjoy them, and not rush through them to complete them like a checklist, for the game to go back into storage.

The biggest thing I am worried about now is seller's remorse.

Will I regret this decision down the line?

Has anyone else been through this?
