I have the 5 1/4" floppy of Populous on my shelf (which is why I knew the year). Sadly I can't play it any more because of the 1980's DRM. Even if I could get a 5 1/4" drive working in my modern PC, the game asks you populations of various world cities for which the answers are on an un-photocopiable (black on dark red) sheet that came in the game box which I have sadly lost.

hmm I just looked on GOG and it's $5.99 http://www.gog.com/game/populous

Annoying though, when you have it already :)

I got the three pack for $15, gog bless. Even better, you get free games too including Beneath a Steel Sky - I never finished that either - I am a happy gamer.

I was wrong about the DRM, that mechanism was Sim City

Populous asks you to identify a picture, which came on a separate sheet from the manual.

It is disabled in the GOG version (although it still asks you the question but without checking the answer).
