I can’t find the ratings for the original (the game may be older than ERSB) but black and white 2 is T for teen. It has sacrifice, murder, child abuse, etc as a mechanic for the “evil” route.

I’m sure there are more games like this. I remember drowning my Sims for fun as a child and I’m pretty sure that game is also T.

I have played cult of the lamb, and there wasn’t really anything in it a highscooller shouldn’t see.
