I bought a bunch of 80s Japanese vinyl records after Christmas. Played them once but otherwise I’m keeping them in pristine condition. If I ever need to listen I have mp3s heck they are on YouTube even
I’ve found Jack Daniels is particularly bad for hangovers for me. Only takes a little bit. I’m usually great at avoiding hangovers but I always get one if I drink that. I have a mostly full bottle of it sitting in my freezer for weeks.
I bought a sealed copy of Metal Gear Solid for the Game Boy Color. I guess that counts.
I just remembered I have a copy of Medal of Honor too that I won't be touching. And Shenmue 1 and 2 for the Dreamcast.
Shit, there's a lot more.
I keep the occasional merch sealed up for a while, before I end up saying "screw it" and put it on display. The only thing I have ever kept sealed and in pristine condition is a hand drawn cover of the Flash by Lee Townsend. It's not even that rare or special, but he was involved in creating the World of Warcraft comics, so I care a lot about having something from someone that was involved.
I didn't want to open an amiibo for no good reason since I'm never selling my collection and couldn't actually care less that they are in the box. Something just made me want to keep pixel Link unopened. Trying to explain that to a 5 year old made me feel like a complete pathetic loser, so of course it got opened.
