You would probably be interested in Good Old Games, www.gog.com.
You can download for $10-$15 old PC games and own them like you used to be able to.
I downloaded CIV 3 from that site.
I love sites like www.gog.com. It is much more of a challenge to get old games to work from places like archive.org. I managed to get You Don’t Know Jack and WAcky Wheels to work in one of my virtual machines a week or so ago. My wife and I used to play them with friends and our kids on a Windows 3.11 desktop many years ago.
I have a pair of SimulEyes 3D stereo VR glasses that work with Windows XP and a CRT monitor with a fast refresh rate. I still have the computer and monitor that I used them with. My favorite games with that system were Descent and Descent 2. The effect was quite amazing. I noticed that gog.com had them already set up for a modern OS.
