I don't take the game itself seriously; it's entertainment, and if you see it as an occasional escape, that's fine. But if it's something very serious in your life, frankly, it's worrying. Try to get help, bro. It's not worth wasting your life like that. Sure, sometimes it's difficult, but it's always worth trying.
I don't really understand that question to be honest, is that more of an philosophical question? Or do you mean if we see porn games at the same level of normal videogames? If second, I definitely say no and that's good, back then games weren't taken seriously too, now since games are taken serious and are mainstream we just get pre-baked early access titles that will fulfill a investors quota. Porn games are mostly a work of love, it's a hand full of people dedicated to make something they'd like to play them aswell
I mean, it is art in my opinion. It by no means needs to be art you value highly or even respect but I do think it's undeniably art. In that way I guess I take it seriously. As I see it, even if its just porn its something made by people for others to experience. Sex is just another part of life and it would be foolish to think that humans would not, or have never, made art surrounding the topic. As for the content of a game? Most of the time its pretty trash lmao
Every porn game? Definitely not, but there's a few that made me invested, the most relevant one being all the Monster Girl Quest games. You might think it was all about monster girl porn, but the story is actually amazing
