I'm sure many are aware, but for those of you who are not, and have an affinity for old PC games...

Just ran into this site a month or so ago. You can buy old games (like early 90's era type stuff and more) for like $5-$10. They are downloadable and can be installed on modern hardware/OS. There is no DRM and once you've payed for it it's yours, no online checks or anything.

Pretty sweet.

edit:
here's a bit what they're all about.
