As part of a coding session, s0lly decided to create a version of Civilization . One based on the original video game from 1991 and made and operated in a Microsoft Excel spreadsheet .
Here is the game in action:
As you can see, it really is only an approximate early days of Civilization with a handful of early game units, the ability to settle cities and explore a map covered in the fog of war. As such, basic things Civ such as diplomacy and the ability to move through the ages are missing.
But this is a spreadsheet so whatever it is! If you want to download and try the game yourself, you can download it here.
