"I look around the office and all I see are the tired pale faces of the Keeper team," reads a rather chilling message found hidden within files for the MS-DOS version of 1997's Dungeon Keeper. "This project has destroyed the health and social lives of each member, so I hope you like the game."

The warning, discovered by coder Christer Kaitila and posted on Twitter, paints a grim picture of the working conditions that led to the creation of the classic dungeon management game, with its author claiming the dev team worked "16 hours a day, 7 days a week, for nearly 5 months". It was developed by Bullfrog Productions, which also made Populous and Theme Park, among other things.
