When I was working in Toronto in the mid-90’s, I was offered a game developer role at a downtown company.
At the time, I was one of the top arcade players on Centipede, Millipede, Battlezone and G-LOC. I had also written clones of Centipede for the PC in C and assembler.
They offered me exactly half the salary of another offer, and expected developers to sit shoulder-to-shoulder around wooden picnic tables. They oozed sketchiness, and I already knew how to write a game, so I passed. But hey, they had a blue screen room! 
I moved into Internet Operations, ending up at Netscape. Eventually I did some consulting for a slot machine product which needed to pass Las Vegas gaming compliance. Small world!
To pass, one of the requirements was that the game had to be guaranteed to start in a known state each time, presumably in case employees or bettors tried to improve their odds by yanking the power and restarting the game.
That guarantee was accomplished by using a journalling filesystem and a built-in UPS with linux services carefully configured to start and stop reliably.
