My friend sold his Video Game Collection, it just made me have a midlife crisis at 29. Is this normal?

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?
