Games with procedural generation

Procedural generation in games refers to the use of algorithms to automatically create game content, rather than having it manually designed by developers. This method allows for the creation of vast and varied game environments, objects, levels, or even narrative elements without needing each piece to be handcrafted.
Procedural generation can be applied to many aspects of a game, including terrain, levels, characters, quests, and even music. Procedural generation is particularly effective in games where exploration and replayability are important.

Procedural generation has been a part of gaming since the old days, long before modern technology made massive open-world games possible. Early games had extremely limited memory, typically in the range of kilobytes or megabytes. Procedural generation allowed developers to create large and varied worlds without needing to store vast amounts of data.
