A little ramble, but i think a huge part of what makes The Stanley Parable so interesting to make content for in the fandom (other than the game itself, of course) is how open-ended it can be. It may have only a few characters and not much development in these characters pasts and whatnot due to how the parable works, but despite this the characters it does have are so interesting and unique, each one of them are. And because of the nature of the parable, where the Narrator can manipulate your surroundings, you can make anything happen without it being drastically away from canon/not possible in canon. And not only that, but you can come up with anything for the pre-parable and post-parable worlds.
I just wanted to ramble about how fun it is to see fan content for this game, because it really is all so unique because the game is so open-ended. The characters are all amazing and it leaves room for you to explore your own ideas without it being a separate AU or whatever, but it also isn't too open-ended in a way that would make characters flat. I love it. TSP fandom, continue being normal about this game. So much of the fanart and writing I've seen has been so unique and good
