Yeah, it’s valid to dislike AITSF. I disagree on literally every single one of your points, but hey, what can you do.
I guess the point I wanted to make (and god do I hope I don’t sound argumentative while saying this) is that the Zero Escape series (and often VLR alone) doesn’t follow the three rules laid out in your post either.
VLR’s also a game that throws the concept of Knox’s Ten Commandents at you, which is a set of ten rules that their creator believed every “good” mystery should follow (ignore the really racist one, lmao). VLR then goes and disobeys every single one of them, as if Uchikoshi’s deliberately going “nah, mysteries don’t have to follow rules.”
I hope this doesn’t sound too argumentative! It’s perfectly fine to dislike or even hate the AITSF series, regardless of whether you’re a fan of Uchikoshi’s other works. I just don’t believe that the ZE series follows the rules outlined in your post, and I don’t believe they’re fair grounds to criticize AITSF on because of that.
