Since somebody shared this nice comic about manuals in games in another community, I was thinking about them myself.
My most cherished game manual was the Diablo 2 one. The way they created a little story for each single ability was such an atmospheric wonder and probably started my fascination with lore instead of story. They were also probably the main reason why I took the necromancer and started to feel bored, when necromancer are automatically evil in a setting. Get creative!
My father had Falcon 4.0 and that was “just” a technical manual in itself. 5+ cm thick and full of schematics of the cockpit. I was in awe as a child about the complexity of that thing.


Simcity for SNES is the greatest manual ever put together. One Lemmings opinion.
Was that one the original, that is now Micropolis in Java?
