My kid's a big fan of original StarCraft, which is now going on 28 years old.

I think you need an emulator to run Civ1, though. My kid was asking if we could try it and I'm like "I don't think I can find that on Steam..."

See archive.org [0], eXoDOS, or eBay and DOSBox-X.

Civ1 was for DOS, but CivNet is almost Civ1 and was for windows... But maybe win16 and you'd need winevdm or something if your install is 64-bit.

AFAIK, you can run Civ1 (and other 16-bit games & applications) on Windows 10/11 in 3 ways:

1. Run CivWin on WineVDM: WineVDM, also known as OTVDM (Old 16-bit Windows Virtual Machine), is a compatibility layer that allows users to run many legacy 16-bit Windows applications on modern 64-bit Windows systems. CivWin is the Windows re-release of Civ1, that's recommended due to its high resolution support (e.g., you can play it in HD with cool mods) and some people like the final multiplayer CivNet release too.

2. DosBox (get the D-Fend Reloaded frontend/GUI, it contains DosBox): https://dfendreloaded.sourceforge.io/ https://www.dosbox.com/mown/index.php

3. VirtualBox or VMWare (virtual machines solution) to install and run a copy of Windows 95/98.

Note that Microsoft removed support for 16-bit subsystems from 64-bit editions of Windows many years ago, beginning with Windows XP Professional x64 Edition.
