> Nietzsche's worldview was intrinsically fascist (or proto-fascist)

Well done for seeing the truth

Like video games cause violence, I guess.

Philosophy is written to inform your world view, video games are made for your entertainment. I think if you are a going to base your world view on any video game it is going to be quite concerning. For example if you take Super Mario as your world view you might start consuming shrooms, jumping on enemies heads, and lighting them on fire

And if you go that route then it's on you, not Super Mario.

Or because of anything intrinsic to the latter's Weltanschauung.
