Chapter 32:
-C-Sha's comment that Rubis's Heart title sounds like a cool name for a pirate? In Marvel vs. Capcom 2, there is a female pirate character named Ruby Heart, and one of the magical artifacts in her collection is a book that allows her to manipulate water.
Chapter 33:
-Activision, the first third-party publisher and developer, is founded by ex-Atari employees who were unhappy with how Ray Kassar, Atari's CEO, refused to give credit and more royalties to his developers in exchange for their hard work. Atari sued them after their exodus for patent infringement, but ended up losing the lawsuit—that's where the "Rei's Oracle" and "greatest traitor in Tari's history" parts come from.
-Filina represents Philips, more specifically, Magnavox-Philips, thus she is a "Fragment of the First Goddess".
Chapter 34:
-Insomniac Games had lent their Luna Engine to Respawn during Titanfall's early development, though the final game is still completed using the Source Engine. That's why Luna "Insomniac" Ratchett is one of Respella's acquaintances.
Chapter 35:
-Ruby Heart uniting the sixty tribes of the tundra is a reference to the sixty Game & Watch handheld variations.
-In Mk2, Mina said the DoS was born in Lowee. It might have been an allusion to the rise of game-copying devices and piracy on the Famicom Disk System, known as "Magicoms" in Japan, and Arfoire's Japanese name, Magiquone, is also referencing that. Since the FDS had a very unfair licensing term for third-party developers, which gave Nintendo 50% rights to all games made on the system, I translated that into the DoS being created as a response to Ruby Heart's authoritarian rulership.
-Delphinus, Blanc's predecessor, represents the GameCube. Her name comes from the console's codename-in-development, "Dolphin", as well as the rumored "StarCube" name that never materializes. Nintendo in the GC era was kinda having an identity crisis, torn between the market's desire for more "adult" games and their image as a "kiddy game" developer, so Delphinus is the only CPU of Lowee who's a mature adult woman.
Chapter 36:
-Agent Massy is, unsurprisingly, based on Massive Entertainment, the Ubisoft subsidiary behind the Division series.
-Rubis slaying a giant ape monster is basically the Nintendo vs. Universal lawsuit (over whether the Donkey Kong games are infringing on the King Kong trademark), but with a real monkey involved. Its name, Megaprimatus, came from King Kong's scientific name, Megaprimatus Kong.
-Silver Heart, Lowee's forgotten first Goddess, represents the Game & Watch handheld. Yes, I know Nintendo's first consoles are the Color TV Series, but these are basically dedicated consoles, each with a single game built into them, much like the tons of Pong consoles an ocean away. I choose to only count consoles with interchangeable cartridges/CDs as a real "CPU", worthy of being personified in the Hyperdimension.
-G&W is the same, really, though with one difference—it has a "Game A" and "Game B" mode, with the latter being a more difficult version of the former. That's kind of like a proto-HDD, isn't it? The in-universe explanation was that, because of the scattered, disunited nature of her adherents, Silver Heart was quite weak and tiny, and her HDD Form was incomplete in the same way that a Candidate's is.
Chapter 39:
-Sosaria Wings represents Origin System, the second pioneer of CRPGs alongside Sir-Tech, whose Ultima series served as the other main inspiration for the JRPG genre when it reached Japan. "Sosaria" is the pre-Ultima IV name for the continent of Britannia, which the Ultima games took place on, while "Wings" is a homage to Wing Commander, Origin's other famous line of flight simulator games. EA's digital distribution platform is named after this company.
Chapter 41:
-The Y-AR jet is a reference to Yar's Revenge, an old 2600 game, while the Tempest-2000 was named after a Jaguar game of the same name.
Chapter 43:
-Mr. Esaka's backstory of unhappy divorce and descent into gambling addiction is referencing how Aruze, a pachinko manufacturer, bought out SNK and caused its first bankruptcy, after which SNK Playmore sued Aruze for copyright infringement in an attempt to regain their game IPs—hence the divorce lawsuit, only that in this story, Aruze won out and took away their "daughter", whereas in real life, SNK Playmore was the victor.
Chapter 44:
-Obvious Gurren Lagann reference aside, "Mode 7" is a graphics mode for the Super Famicom/SNES, which allows background layers to be rotated and scaled, creating a pseudo-3D effect.
Chapter 47:
-The Legend of Terra and Tarr is a Swordquest reference, based on the names of the games' twin protagonists, Tarra and Torr. Basically, Swordquest is Atari's unfinished video game series, where players participate in contests to win five real life treasures. Only two were obtained by players, before the contest was cancelled during the Great Crash, and the remaining treasures were lost forever.
-The specifics of the legend, however, loosely mirror the history of the Tari nation in-universe: settlers of the New Tari colonies on PC Continent (the Atari 400/800 computers) sailed back to their homeland, and rebuilt the nation after the Great Shock, with the aid of the Commord Emperor's heirs, who were being prosecuted by the Ami Lorraine usurpers (Jack Tramiel's ousting from Commodore, subsequent takeover of Atari, and the Commodore Amiga).
