I don't believe all of what ICSTOR says is bull, it's more exaggerated truths or half-truths. There maybe facts to what he says but he twists them to fit a whole narrative he can dance around.
Like we've just "proven" (I'll use the term loosely) the dialogue + scripts (code) does exceed 900 pages with no line breaks, since he's not only changing the dialogue (the things we see) but also some interactive stuff on screen which is embedded in the code.
Do I think they cycled through 900 pages of that crap? Hell no, dialogue was easily around 100 pages to clean up. Code was probably about a few hundred more too. Also Ctrl + F and replace variables with a search, they are not manually doing this.
That exaggerated number was simply there to show how "hard" they've been working and sweating when it doesn't truly reflect the actual changes but the overall size of the problem (BIG difference -- correlation does not necessarily mean causation). Don't get me wrong, they've probably been cleaning up old code in the process as well as they mentioned and just been hanging around for the review (that part I believe since there's a ton to sniff through).
The 900+ pages is still bull when we've confirmed the dialogue isn't even that large, most is just junk code pointing towards "suggestive" variables in a wrapper.
Also it isn't like he has to re-write the WHOLE GAME!! Just Celia's part. The sleep sex just do away with it or add in a scene where Linda (and maybe a few others) tells him it is ok for him to come play with her at night while she sleeps. Sara being younger and in a class below him. Simple just add in a scene where they talk about how he was sick one year when he was younger thus he had to repeat a year. So him and Sara are both now in the say year. They just take different classes.
