There are very, very few games I ever return to after completing them. There’s just always something shinier and newer to play!
That isn’t to say at one point I didn’t care deeply about this sorta thing; I had several large cardboard boxes filled to their brims with every game I owned. Unfortunately after dragging them from rental to rental to rental I found myself stuck in a position where I had nowhere to store them, needed some quick cash, and was just generally resentful of the expense/hassle of lugging them around. In the Marie Kondo sense (tho she wasn’t on the go back then), they just weren’t actually bringing me much joy.
So I made the decision to get rid of the lot, save for a handful of titles which were outstandingly meaningful to me in some way (i.e. UFO: Enemy Unknown was the first game I ever owned; an at-the-time unwanted* birthday gift. I’ve still got it, currently on the shelf above me. I doubt the floppies work.).
Most ended up on ebay and, upsettingly, I got next to nothing for them. It was barely worth the effort; there’s a lot of time consuming admin involved with photographing and creating those listings and after ebay took its cut and a couple fell foul to scammers I made a pittance. The ones I couldn’t sell I made the decision to just throw away, though I did save the discs for some in one of those CD wallet thingies.
The experience was, in its own way, heartbreaking - I was casting aside a good chunk of my life up to that point. However, as a result of that I’ve been a lot less concerned with the material nature of this sorta thing. I’m in it for the experience alone, and the replay experience is never the same as the initial one; there’s probably only one old game that still has any meaningful impact for me.
Anyway, not really an argument or an attempt to sway opinions; just sharing some melancholy personal philosophy… Which I have no idea how to apply when the physical version is 17 quid cheaper. =\
* I’d played the demo, had no idea what I was doing, got everyone killed immediately and consequently thought the whole thing sucked. So that was one miserable birthday present - “But you like sci-fi aliens! And it got good reviews!”. I begrudgingly played it - my parents didn’t keep the receipt - and, ok, maybe after awhile it kinda maybe didn’t actually suck. Entirely.
