I suggest you research computational theory and then run the math, the complexity of the issue you want solved is beyond our current scope of technology
Anyhow, we have computers that can generate content based on images from real life, perfect replicas of environments yet I don’t see people preferring that over the same environment drawn by an actual person, or to put it in simpler terms:
People like content generated by other people, not computer generated content this is because the content created by humans has slight imperfections giving it personality, something the computer generated content does
Besides, I don’t think you understand game development for your idea to work someone would a) have to write a game engine that can handle every theoretically possible scenario and all the theoretically impossible ones as well since theory only takes it that far, already there we have an infinitely long workload (because there is an infinite possible scenarios and variations of said scenarios and the engine would have to handle them all)
But let’s invoke the Infinite Monkey Theorem, now we have the engine, that’s cool now we have to write an AI that can interpret the text the user inputs, no matter the language (we can’t be discriminating non-English speakers here) and we must also make sure it can decipher the text no matter what is inputted, this means it must handle text like l0l, 1//\46!||3 @ 6@3|/| //3RZ J00 R P07@70 &&& đ1!3Z P1||Z!11!one! or I wnt gm wr shtng nd xplsns wif prty bebs nd gnt rbts., and then we must also make sure said AI can read their minds as to make sure that they do exactly what was originally intended in the first place, otherwise the customer will call it crap because it didn’t make the intricate game they imagined from their pathetically vague one sentence description
Oh and that is still not taking into account that it would have to be able to generate all dialog, all art and all sound on the fly as it creates the game, or perhaps we could invoke the infinite monkey theorem again and thus generate the entire infinite art, audio and text library required for such a game.
Now a more realistic scenario: Learn math, Learn programming, Grow the fuck up and stop whining, creating things is hard, that’s what makes it worth doing.
P.S You are one of the groups of people I can’t stand, mainly the group that thinks game development is oh so easy. You disgust me and I want to punch you, in the face, really really hard.
