It's a video that takes 6 (I think) obscure horror games and analyses the mechanics behind them. Ao Oni was one of the games.

It's driving me crazy that I can't find it. I don't remember much about the youtuber other than that he has this weird obsession with that guy from id (thinks he's a genious) and that I think another video he did centered around unknown gaming firsts. If I remember correctly, he had a lot of videos on stuff like counter strike and PC jargon.

I feel like no on will know what I'm talking about, but it's worth a try. I need to bookmark that video.

Maybe it's in your YouTube history

Did you watch it recently?

If so, check your YouTube/browser history.

No, I watched it months ago. Like 6 months or so.

It might still be there if you commented on it.

I probably didn't, and I watch way too many youtube videos to be able to realistically find it that way.

If you was signed in when you watched it, it will still be in your watch history.

I'm not sifting through 1,000+ videos.

Ok, good luck finding somebody who knows the video then.

A quick google search gives me this:

I'm on my phone and I'm using LTE so I can't check it out, and tbh I doubt that's it, but I guess you could check it out and see for yourself.
