I found myself thinking similar recently. My gaming time is limited, and when I fancy playing something it’s easier to open an emulator, and flash carts etc anlso add a lot of moderns conveniences to playing on real hardware also. I had a whole shelf of boxed Nintendo games that I rarely if ever played because I didn’t want to damage the increasingly fragile boxes.

I downsized my collection to a few favourite systems and it’s turned out for the better. The money raised from the bits I sold has been well spent of other interests/projects, and the things I’ve kept I’m getting more enjoyment out of.
