>>24520900His influence was titanic.
I come at this from the angle of a film buff and a chosen "Homo Ludens", which is a perspective I don't think many dedicated /lit/izens share.
I'll try to keep this roughly chronological
>SupermanSelf explanatory. The original Superman comics were directly inspired by Nietzsche's writings. Particularly the idea of the Ubermensch helping others by the abundance of his strength and spirit (as opposed to by striving or moral dictate).
(This is mostly what I mean by "for worse" - Nietzsche is directly responsible for the creation of the Superhero genre, which in the West has degraded into the worst sort of pop entertainment).
>Astro BoyJapan's take on a Superhero and the very first anime. As the Japanese were allied with Germany, Nietzschean philosophy became popular among their intellectuals, and his philosophy is at the genesis of anime itself.
Astro Boy "The Mighty Atom" is a nuclear powered boy robot, which is meant as a heroic Japanese response to nuclear weapons: to make a hero of nuclear power is to stand tall against their tragedies.
To continue this train of thought, Gundam, one of Japan's most popular anime series, ongoing from 1979, is also an overtly Nietzschean series. The original 3 shows and conclusion movie following a Nietzschean aristocrat and his moves against the masses.
From the legacy of Gundam you get Neon Genesis Evangelion. From both of these, you find their influence everywhere in Anime and Japanese videogames.
>2001: A Space OdysseyThe opening of the movie is set to Thus Spake Zarathustra by Richard Strauss, and the film follows man's evolution into Supermen in the Zero Gravity of space. The symbolic significance of Zero Gravity will be familiar to anyone who has read Thus Spake Zarathustra.
2001: A Space Odyssey was the first successful "serious" high budget Sci-Fi film in the western industry and defined the aesthetic of Sci-Fi filmmaking for decades to come.
It was followed soon after by George Lucas' Star Wars, then Ridley Scott's Alien and Bladerunner.
Bladerunner is also a deeply Nietzschean film. Roy Batty is Nietzsche's "Blond Beast", who kills his own creator (death of God, etc.).
It should go without saying how much all of these films have influenced the rest of culture.
Just as a random specific example of this influence, Alien of course has its sequel Aliens.
Both of these directly inspired the Metroid series of videogames, which is ongoing and includes some of the most highly rated (and overrated) videogames ever made, including Metroid Prime which was hailed by journalists as a 10/10 masterpiece and "the Citizen Kane of gaming" when it released.
There's the Halo series of games, which are heavily influenced by movies like 2001: A Space Odyssey and Aliens, and it was the first videogame series to make more money in a single year than any hollywood blockbuster, in 2007 with Halo 3.
These influential examples all owe much of their originality to Nietzsche.
