Yeah, that really does calm me. I have some old systems and games that still work on them... even a Nintendo. I almost mentioned it in the previous post but I realize how actually transient even hard copies can be. Trying to install some of my oldest PC games by disc is a nightmare.

I'm sure that once upon a time I could've bragged that I had the hard copy of some game on 5.25" floppy, but what the hell good would that do me anyway? In 5-10 years I might feel the same way about DVDs and my collection of hard copy game discs will be even more worthless.

Emulation really made me aware of how technology will always change in a way I'm not expecting and so it might still with the games in my Steam library... for the better. They will always be accessible in some way.

And like you said, Steam is super solid and staying on top because of their service angle. So long as that's the case they will continue to be the leader and I'll feel safe about my library. I also have the feeling they will evolve with new technologies rather than get eclipsed by them.

And even if they don't, until the inevitable future, I'll use the service that's the best out there by a long shot.
