I've been selling off a lot of my collection: both games I played and some stuff I never got around to. For example, at this point I'm never going to play my unopened (or any, really) PSP games . I even sold a Gran Turismo PSP hardware bundle I simply never got around to opening. For whatever reason it sold for more than I paid for it - I guess to a collector. So it hasn't all been cheap stuff. It's been nice as the only reason I could justify dropping $500 on the Series X is that I sold at least that much worth of stuff this year.
I was cleaning out my old stuff and was thinking about doing the same.
Did you sell piecemeal or all together?
I'd rather sell my collection of original Xbox Tony Hawk games as a collection then trying to ship them for $10 a piece.
