The N64 is a weird console for me. It was a time when I had a lot of free time & it was the first console I bought with my money... but I'm not overly nostalgic for it for some odd reason.There's only about 5 games I'm drawn to today & they all emulate fine. This one I don't regret selling due to money value or because I sold my childhood...
First, you have to understand my house set up back then. I had this decent sized TV stand where the bottom half was made to hold media. Our entire home's VHS collection was in there. I was told to not tear them up so I left it alone unless watching a movie. It taught me to take care of my media. A habit I still am OCD about today.
Well... in that closed entertainment center goes my N64 game boxes as I get new games. I take the cart out, put the box up & they all go essentially unhandled. I traded in all my N64 stuff to go towards my Dreamcast. That honestly was worth it looking at dollars
made compared to owning a DC for me.
I do however regret handing over about a dozen MINT N64 game boxes and the system box to Game Stop. I had no idea as a kid/early teen you got the same trade in boxed or not. Highly likely they were trashed or not sold to the next game owner & lost in the shuffle

.
So I regret it from a preservation point of view versus monetary value or losing a treasure from my youth.
I've heard of several folks who trashed their Saturn boxes. I known another member here did that as well but at least kept the manuals. You had a Jaguar CD during its relevance... that's ganster.
