My friend and I collect old video games. But all my physical media just sits on my shelves and collects dust. Why do I even collect them? I literally just emulate everything. Is there a purpose to what I do? People ask me why I collect and I never have a real answer because I don’t even know. If I never play my stuff, is it worth just selling?
You probably enjoyed collecting it. That means finding the games and then putting them together in a neat collection.
You probably did it because you enjoyed finding the games and wanted build the collection because you thought you enjoyed owning them as well.
Goals change, priorities change. Appearently he didn’t enjoy it anymore, and that’s fine. It’s probably hard to realize that you no longer share the same joy about it with your friend.
That said, that has nothing to do with whether you still enjoy it. And regarding your questions: do you? If so, it’s totally fine to own something just because you enjoy having it around. Maybe if you need the money urgently or the space, there’s an argument there to trade that for you enjoyment of this, but that’s up to you.
I hope that whatever you do, it’s because you decided it for yourself and didn’t decide it because of whatever your friend did :)
