I am fundamentally opposed to the idea of adapting the Backrooms to RPC. Especially with a silly knockoff name like "backspaces". It's a paper thin layer of "legally distinct" that serves zero purpose except to somehow communicate that "this isn't the backrooms it's different" when it clearly is just the Backrooms. Not just that, but the entire way you depict the Backrooms is straight up taken from other sites, down to the Level bits. That just doesn't sit right with me.
The terms used make marginally more sense than in the original poorly-designed worldbuilding but that doesn't excuse you just transplanted a fictional universe to RPC without even providing anything unique of your own design except a once-over with RPC colors. The only reason I can't call it a ripoff is because the concept is too widespread to be ripped off, but you don't have the justification alternate sites about the Backrooms do where they seek to provide a different interpretation of the same universe.
To add to that, the Backrooms do not fit on RPC. The entire thing that makes the Backrooms is a sense of isolation and being out of your depth. Placing it in a sterile, clinical setting takes a lot away not just from the presentation, but the entire theme that makes the idea spin. It loses its identity, which is something that a lot of Backrooms-dedicated sites that use SCP-like formatting are criticized for.
To be clear I'm fine with crossovers in a minor fashion. Referencing or alluding to the Backrooms in RPC or vice versa is fine, and the shadow of an RPC-like organization in the Backrooms would be a nice mystery to add to the universe, but they're too fundamentally distinct to go for anything more than that. The degree of tonal clashing between both concepts has a campy effect in the same way as fanfiction, in the sense that there's such a fundamental disjointing between both that you need to shut off your brain to enjoy it without cringing out of existence.
If you really want to do Backrooms in RPC, make your concept distinct. Grow it in different ways, take it in a direction that works better with the fundamental tone of the RPC universe. Do Backrooms-inspired instead of literally just the Backrooms. You will absolutely need to remodel the whole thing from the ground up rather than just giving it a paint-over. RPC-794 does a vaguely similar thing, you can take something like that and go from there.
This has nothing to do with your skill as an author. It's plain and simply a stupid idea.
The Sector-100 link is an equally stupid idea. S-100 is such a great and compelling mystery because it's out of your way, obscure and oblique. It works because all of the pieces are immediately inviting and don't mesh together into a clear picture even if you find multiple parts of it. It's compelling because of how subdued it is rather than because there is an RPC explaining what happened and why the incident was so catastrophic — there's a million "big catastrophe" storylines in which the Authority has to cover up a mistake or containment initiative, of which I've written enough to be tired of the concept. There's only one Sector-100, and it already grazes so close to ruination with the LAI that explains way too much and takes too many cues from SCP's Site-5 ("personnel are to be reminded that there is no Sector-100" is fucking plagiarism and you should take that off of your work at least out of self respect), and the Anomalous Event that does far too much exposition to work.
Furthermore, what in God's name do the Backrooms have to do with any of the themes that tie Sector-100 together? Why does the destruction of the gateway to the Backrooms make Sector-100 become a ghost haunting the Authority database? There's no way to connect them in a manner that isn't insanely contrived and doesn't provide enough exposition so as to ruin the concept.
The Black Site link is an equally stupid idea. There is no clear reason for this discovery to be any worse than the already insane shit that the Authority handles on the regular without needing the super secret body cleanup crew to handle it. It's just an alternate reality: we have at least a dozen of hostile ALTRs that don't need Super Top Ultra Secret Classified security. It feels like you added BS because it already was in the Sector-100 LAIs without justifying it within the text of the article — which might not be true, but that's what it initially felt like to me. Funnily enough, Black Site already has a Backrooms style concept in the lore — which is a part of RPC-000. It is equally stupid in that article and I have lambasted it to oblivion already.
You really should take the entire concept and reconsider it. This is not going to work the way you're doing it. I hope it doesn't hurt that I tell you this, but it absolutely needed to be said.
If you'd still like to run with this current idea, tell me and I'll run a line-by-line.
Foregoing my criticism of the poor diction and clinical tone, since there is a fundamental issue with this article. The following is a copy-paste from a previous article that attempted to execute the same premise of "What if internet concept x was an RPC:
This is a very common thing throughout containment fiction that persists to this very day. However subjective, inputting already-existing character types/concepts to the wiki with an RPC-spin is not and shouldn't be acceptable writing. Taking something that already exists and presenting it in an RPC format and/or with the premise of its interactions within the Authority universe is lazy writing. We see such things almost every day already on YouTube and whatever other social media that comes to mind. The RPC wiki exists to fill a niche of concepts that have yet to be explored in an immersive manner. If we continue to high-rate content that consists of objects like this article—concepts that already exist in pop-culture or even in quieter subcultures (Sirenhead, Slenderman, The Backrooms for instance)—this wiki will stop looking like an original project and will essentially be another Weegeepedia, wikis where RPC-Spiderman fights RPC-Trollge to win control over Pepelandia and all other types of stupid recycled garbage that only a 12 year old would take the time to read.
It's for this reason that I fundamentally oppose this article and the idea of it being posted to the wiki.
Now, this isn't to say that one shouldn't write anything similar to what already exists online,
there are plenty of successful articles that are genuine good reads despite being heavily based upon characters/icons/etc that already exist. The reason those articles are successful is because they subvert the expected notions that those well-understood things possessed in a way that invokes the themes of horror, creepiness, and general weirdness, and these are precisely the kind of concepts that the RPC format does exceptionally well. This article of course does not sport any of this, it is in fact generic in its presentation of beaten-to-death concepts.
But there is even more of an issue with this article, likely even more important than the first,
You have directly ripped off concepts from Backrooms/Liminal Archives to use in your article, "levels," the proposition of communal societies, etc. These are all concepts that belong to the former wikis, and as such I view as plagiaristic, in a loose sense. I cannot come to the conclusion that you created such concepts originally by yourself, I reckon you must have viewed these wikis and thus decided to rip them off. This is irresponsible, unfair, and shit writing.
I usually write crit that is a bit more comprehensive. But, this article is an exception.
Without sounding too much like a parrot to previous commenters,
This article seems too heavily inspired from the Backrooms.
The terms are slightly different, but "first sub-space of the Infinite Plains, formally known as “The Corridors”" isn't much better either. It doesn't help that this article itself doesn't bring anything particularly interesting to the RPC-scape or Backroom-scape to justify this level of inspiration.
It was a bit challenging to read this article, just because I am not usually interested in Backroom-style content, and this article seems nothing more than a transplanted Backrooms article. I find their structure to be a bit boring and their lack of clinical tone to be disruptive. This article suffers from similar issues.
The idea also seems to be a case of "something but ooh anomaly". Such articles can work, but this is certainly not one of them. There's no subversion that justifies making this "something but ooh anomaly".
Usually, when I end my crit, I provide some suggested reading. This time, however, I am unsure where to begin in terms of reference material - there are structural issues with this article and this article probably deserves a bit of an overhaul.
