Something I was thinking about the other day. When X-Wing came out I remember playing it to death, for example. Now I suppose you can play it if you can hold of a version and some kind of emulator for a 486 DX50 PC and soundcard, but you might end up with the Win 95 CD version they did later that had a rubbish change to the music.
Anyway, there are plenty of games I remember that completely owned me but I'm not sure how easy they are to play now. They could well crash half-way through or involve a lot of jiggery pokery to get running. And emulators aren't always as close as the real game was. Like if I booted up an old C64 game I'd need to find a good joystick to get the same feel to it.
Books, physical toys, board games, even TV and films are all still available to use and play in one sense or another. While modern kids might well just not like an old game you loved that's the same as a TV show or film, etc. but the difference is they could at least experience that entertainment as you did.
Oh well, tl;dr.
