Sitting on my desk just across from me is my copy of the original Civilization manual. It’s a relic of a bygone age: 129 pages long; written in a single language meaning all 129 pages are relevant; and just chock-full of information about how best to play the game. Twenty years ago this is what manuals for complex strategy games like Civilization had to be – while the game had what was for the time a very advanced in-game encyclopedia and tips system, dedicated interactive tutorials that taught the player to play as they played were not yet a thing. They couldn’t be; games came on a couple of floppy disks and computers and development philosophy were not yet mature enough to implement that sort of advanced feature.
