Same here, haha, between my early days of game collecting and then Steam sales fever, I have so many more games than I'm realistically going to be able to beat. Plus I'm a bit of a datahoarder, so I have everything either on physical media, and the respective console to play it, or backed up on drives, and I plan to further improve my storage in the near future, so even if Steam or the entire internet goes down, as long as there's electricity, I'm good

Assuming Steam survives, or your console manufacturer keeps releasing updates, or whatever.

In the cartridge days all you needed was the console and the cartridge. As the years go by, you rely more and more on online services, software updates, and so-on. Even for supposedly offline single-player games, many of them stop working eventually.
