Fun little bit of computer history: the Atari game "River Raid" (available on some flashback consoles) uses "randomly" generated landscapes and obstacles, but it's exactly the same every time you play it.

It uses the same seed on its LCG when you start the game, so everything else is deterministic. As far as I know it's the first procedurally generated video game.

"Pitfall" for the Atari 2600 uses the same approach for laying out obstacles, with a carefully tuned seed that produces a winnable game world with reasonable difficulty progression.

Another 2600 game, "Entombed", has seen recent enthusiasm for a novel automata which generates aesthetically pleasing and mostly-solvable mazes with a minimum of working memory.

Rogue is two years older than River Raid and also used procedural generation.
