Hi
I'm just a fan, but a thing i can awser a few of your questions
1. It has already been said that the gallery, if it exists, will only be for scenes that cannot be repeated. Not to mention that the main reason why a gallery isn't a certainty is that it demands time, time that most people prefer to invest in new scenes
2. There's not much to say here; it's been said many times that this won't happen
3. That's a really cool suggestion, i would like to see it
4. I find it difficult because Dr. Mura has said several times that one of the things about the game is that "choices have consequences," and if you know the consequences, it takes away some of the essence that the developer wants it to have
5. Being funny it's part of charming
