My parents never really comprehended the potential value in boxes and cartridges so a lot of my old SNES, Mega Drive, Gameboy, and N64 games got flogged at car boot sales for criminally low prices. (Like they sold my SNES with Super Metroid, A Link to the Past, and Yoshi's Island for £15...)

I always tried to keep games in their boxes (even the cardboard ones) as much as possible, because I liked having a "collection" to look at on the book shelf. These days most of my collection is digital due to living in the Parisien area which means apartments are tiny, lack of storage space etc. and I don't plan on staying here longterm so I wanted to keep the number of physical items I hoard to a minimum. Once I'm somewhere I imagine living more longterm, I full plan on retroactively building up a boxed collection (even if it's going to be a costly endeavour...)
