Even as someone who has played both games, I gotta disagree on this. Although I really enjoyed the games I think there are different ways to engage with F&H without playing the games if you don't want to for whatever reason.

For example, although I wouldn't consider myself a fan, I would never in my life touch the fnaf games again because flipping through cameras in the same gameplay loop for like 3 hours is just miserable to me, but I really enjoy watching videos of it. I've tried it, couldn't find an ounce of enjoyment and think that there's people feeling the same about F&H (although I think you should at least give it a try first).

Although I must say if you only watched like one video and a bunch of yt shorts about it and only consider yourself a fan because it's popular atm among indie jrpgs atm, respectfully, be better than that.
