I'm Saying It and Not Taking It Back

Major things they stole:

Their villain, Silas, is Matthias. Literally, that's it. He's Matthias.

Silas is an immortal man who's been alive for almost 200 years and was a member of the Westchester cult, where he knew Cora. Matthias is an immortal man who's been alive 200+ years and was a member of the Westchester cult, where he knew Cora. Silas wants to sacrifice redfield Noah due to his connection to the Power as part of a complicated ritual he's put together in order to... I'm not quite sure what, exactly, as the story was a bit hard to follow. Matthias wants to sacrifice Rowan, due to their connection to the Power, as part of a complicated ritual he's put together in order to gain more power and freedom and heal the corrupted Power. Silas thinks he’s all manipulative and the main crew states that "He’s getting us to do his work for him!” Matthias thinks he's all manipulative, and gloats about being a "puppet master" and getting people to do his work for him.

And then there's his appearance. That's literally the same hairstyle - even has the part on the same side and the same curly swoops. He's the same age. Same race. Literally, just like Connor in their story is a recognizable AI-version of his in-game sprite, that's what Silas looks like to Matthias. All he's missing is the beard.

The gang's base of operations is Cora’s cabin

This one is interesting. It's such a tiny detail, and I'd grown so used to the cabin being their safe place that when Connor was like "We need to get back to the cabin" it literally took me a moment to realize - wait. They had nothing to do with that cabin in the original series. Using that as a home base was literally our idea, an It Lives Within original.

The main enemies are mind controlled townspeople working for Silas

Instead of following the precedent of the previous games and having the enemies be Power-twisted animal monsters, they decided to make their enemies humans that are mind-controlled into zombie-like beings with that attack the gang in hordes. This is a rip-off of It Lives Within's horrors, which are power-corrupted townsfolk that Matthias takes advantage of to oppose the main crew. And on top of that, they copied the carnival scene where Harper drives through a horde of horrors, including a scene where Devon drives through a horde of mind-controlled/zombified townsfolk.

Noah and Devon's relationship

Their relationship in this '"TV show" has suspicious similarities to their friendship/romance routes in ILW. They made Devon be redfield Noah's anchor to reality, and even had Devon use memories to help ground Noah, which we showed in the cabin scene where Devon and Noah play baseball together. And I know there were Noah x Devon shippers outside of me before ILW released, but it was never PB's plan to canonize them. So the fact that they are seemingly changing course to canonize them after they grew so popular in the fan version feels a bit too coincidental.

Scraping fan art for their AI animation frames

But what's even more egregious is that they have even stooped to scraping from fan artists, who have nowhere near the same following or exposure as our project does. Seriously, what are the odds that the MC they choose to use matches this artist's MC's race, gender, hair, and outfit exactly, that they used Noah's old outfit, that they are literally positioned on the same sides of the image? It's blatant plagiarism, and it's despicable. @errajay I'm so sorry they did this.

These are the biggest similarities, but considering that it was only like 15 minutes of content, that means that a high percentage of the story was stolen. Sure, the exact details of "Silas's" plan are different (he's like a horcrux for the "entity" aka power and he was split into 43 parts and Noah's one of his parts and he needs to kill him to get it back and be free or something) it's the same concept: immortal man who's trapped making a complicated ritual requiring sacrifice while manipulating people to get everything into place.
