When I was a child, I was thinking how amazing it would be if I could store all my games floppy disk on a single, network-accessible drive so that I could access them all without installing and swapping them all the time.

Nowadays I have a NAS that stores both the raw media and installation scripts for those games, and I have wine/dosbox/mame/mess startup scripts for many of them. Can't say that my inner child is disappointed about that, but building and curating that system took a lot more effort than I'd like to admit.

I don't buy games that require online activation, because I can't store and play them the same way. My inner child is very disappointed about that.
