Seeds, in procedurally generated video games, are basically identifiers for the world that's generated. They're random strings or codes for specific worlds, and you can also sometimes input a seed into the game to play on the exact same world, with everything in the same place, that the seed is associated with.1
What's the origin of the word 'seed' being used in this context? It's a pretty ubiquitous term, but it doesn't quite match its usage (at least for me), so I'd be interested to know how it came about.
1: At least as far as I understand it, which is probablyprobably apparently wrong.
