The devs have said they currently have no intention of implementing NSFW scenes into the game, but it does discuss and even allude to NSFW situations. I take that to mean there will be no explicit scenes in the game, though themes of sexuality will be present.
They are also open to NSFW fanart and the like.
A version of Doom was released for the Super Nintendo. This project emulates pretty much precisely the limits of what the SNES was capable of rendering as pseudo-3d graphics.
I don't know what PSX games you've seen, but even the worst of its first generation of games looked substantially more advanced than this.
Having no way of knowing it was sanctioned also means having no way of knowing it wasn't. Which also isn't true, because, you know, you could've used this amazing secret technique known as "asking." It's a far better approach than being a cop.
I know you're trying to apologize, but it doesn't seem like you understand that jumping to accusations was the problem, not you simply being factually wrong.
And that's forgetting the fact that it's very obviously a fan game.
Just a friendly bit of advice: Don't speak authoritatively on historical matters you lack the intellectual courage to actually learn about.
Trans people are not some modern invention or whatever transphobic garbage you're suggesting here. Hiro's story seems to take place in pre-nazi Germany, which was in fact at the cutting edge of sexual research and queer rights advocacy from foundations such as the Institut für Sexualwissenschaft in Berlin (the very institute whose books were the first the Nazis gathered for book burnings, fyi)
Hiro's identity isn't forced, it fits well with the story's period AND he is precious and I would kill anyone who would try to harm him.
Don't wanna pick favourites because there isn't a single bad song in the soundtrack, but Personal Elegy with the Hinterlands as a backdrop works so well. There's something about its mix of electric guitars and steel pedals that makes a road trip through the south feel right.
To get that first achievement, you have to do at least seven of the following things throughout the Hinterlands Ch 3:
As for the other two, it all really depends on how important completionism is to you :)
I'm definitely not going to be getting those.
