The real story of "Thats not my neighbour" is that the doppelgangers just want equal living conditions in the light of housing crisis

Some of the masked characters look like they're auditioning for SlipKnot.

i like how doctor w. afton turned into springtrap, now i know that the games naming was intentional

7:02 these ones are a reference to Ex-Slipknot members who passed away, first one is their old drummer and the 2nd is their bassist

[Tailfeathers]

It’s worth noting a lot of these monsters are named after mythological figures
Ishtar Eshkregil is named after two Babylon goddesses: Ishtar, goddess of sex and beauty, and Eshkregil, goddess of the underworld
Ah Puch Xilbalbá is named after an Aztec/Mayan god and a mythological location: Ah Puch, god of death, disaster, and darkness, and Xilbalbá, the underworld

Surprised you didn't mentioin that Izanami Yomi's look is a reference to the entity from the The Ring.

11:14 The BIGGEST number that can be written in roman numeral is 3, 999 which is written as MMMCMXCIX. 3, 888 is the LONGEST when written as roman numeral, MMMDCCCLXXXVIII. The question is a bit confusing and ambiguous.

Roman numerals have a rule that you can’t use the same letter more than 3 times in a row, You write 3 as III, but 4 not as IIII, so instead it’s written as IV, with V being 5 so it’s calculate as 5-1=4. This process repeats every time when your letter repeats 3 times in a row, and it’ll turn into a new letter. New letters appear again at 10(X), 50(L), C(100), D(500) and M(1000). There’s also another rule that the letters that represented 5s(V L D) can’t be repeated at all, so you cannot use VV as 10.

Teautates and Ah Puch, are clearly based off of Joey jordison and Paul Gray, two deceased members of slipknot. Seriously, their designs are almost spot-on with the masks.

Fun fact: Chaugnar Faugn is a reference to H.P. Lovecraft’s Chaugnar faugn sharing the same appearance being a humanoid with an elephant’s head
Edit: I only know this because of Abella from Fear and Hunger Termina, because her monster form is ALSO a reference to Chaugnar Faugn

[captainsawbones]

The swirlface guy is also a reference to an old creepy pasta about a cursed game that later got created for real - hes the usher in a theater thst goes swirlfaced and chases you after a while if you keep pushing

[agustofurrywolf]

So basically in Nightmare mode we find if Humanity, Non-Human, and Monster Entities coexisting with each other, except for the Doppelgangers???

Very interesting for me at least (I know I know if the characters in Nightmare mode are just straight up remodeled from previous characters or taken from other media outside the game)

[ChaoticGoodGoose-shtw]

I thought the lore reason was that nightmare mode happened in the doorpersons nightmare, which is why all the neighbhors are all crazy looking

[DANGERINTHEFALLS]

The VIP gang reminds me of some of the bosses in Little Nightmares 2

[luckymii]

7:15 Looks like Eren Yeager's final form, as least the head reassembles it to me, so it would make sense why that entity was an annihilator, causing a large scale destruction to humans in that world maybe....though it's probably all in the (doorman's/player's) head...

[seiryunohoushi]

The translation given from that latin on the nurse's entry is actually the story given in Silent Hill about the creation of the cult's god.

[SpyrGaming]

4:58
Shub Niggurath is a WILD ahh name

[CorImpetum]

insane how he didnt mention lilith is a evangelion reference, dissapointed

[AlliQue]

Is it just me, or does Barbatos look almost exactly like Baraka from Mortal Kombat?

[KaosMunkey]

Teutates Taranis and Ah Puch Xilbalba Is a reference to Joey Jordison and Paul Gray from Slipknot

[ImmortalAbsol]

Drugia has 9 eyes not 7, that sort of slip up will get you killed 😋
