That’s not a typo, by the way, it appears it was common to spell Baghdad without the ‘H’ until about the time of the Gulf War… I guess exposure to the correct spelling was fairly limited until that time. Anyway...
If you show a sheet of graph paper and an HB pencil to most people who played games in the 80’s, they will be immediately swept away on a tide of nostalgia to their era appropriate childhood bedroom: Lamborghini Countach poster on the wall, barely used Big Track in the corner, and a self-drawn map for the latest ZX Spectrum game bathed in the radioactive light from a television the size of a small family car.
Personally, however, I would be swept back to a maths class: Trigonometry poster on the wall, barely used overhead projector in the corner, and me dutifully plotting the reference points for a parabolic curve.
It’s not that I wasn’t playing games in the eighties, it’s just that I wasn’t really into the sort of games that required a map to play, I can’t even tell you why. In later years I came to love Metroidvanias and other adventure games where referring to the built in map is essential - but I was never interested in creating cartography for myself - something that many players of similar vintage consider an essential part of the experience.
Certainly, ‘Sceptre of Bagdad’ is borderline impossible without a map and, as such, feels borderline impossible to me.
