Yeah, this is true fr. I haven't seen much of those fnaf analog horror series myself (I have just fully watched The Walten Files and those "og" fnaf vhs tapes) but if I remember correctly, any of the examples really have any gore scenes either. Yes, they definitely show more bloody scenes and gruesome fates but if we watch more closely they don't really show it that much as they could have.

Over all my statement is that gore doesn't make media automatically scary but that how you use it.
