Missing Episode: Newgrounds viewers would never see The Movie (leading to confusion when the season 3 finale references it), the Anime Openings, or other supplemental material. These things were originally uploaded to Fireball20xl, which has long since been shut down.
Keep Circulating the Tapes: As such, the only way to see any of these things is if others who had the original .swf files post them online elsewhere.
Promoted Fanboy: There was at one point a call for fans of the series to submit avatars for use as "extras". Most of the Netkings also seem to be Fanboys or Fangirls.
Talking to Himself: Happens a few times due to the limited cast, most notably with Kirbopher and Zetto (who are not the same person here like in the reboot).
What Could Have Been: There was supposed to be a season 4 of TTA, but it was unceremoniously cancelled after Niosi entered college. A good portion of the fanbase was definitely not pleased with this outcome. And it's a shame, considering the material prepared would've been grand in scale and epic as hell.
Write Who You Know: Most of the characters in TTA and TOME are originally based on members of the TVTome forums. Kirbopher15 and Zetto are both based on (different aspects of) Niosi himself, Alpha is based on his best friend Mike Luckas (Ultimate Creature II), and Ruri and Flamegirl were based on their respective girlfriends at the time.
Martin Billany was born in Knutsford, which is where Nylocke's player resides.
Asterob's, hat glasses, and his tendency to use mannerisms portraying him as an apologetic brit have been said by Niosi to be a reference to the actor who plays him.
Ravenfreak's voice actor is... well, a voice actor (Lucien Dodge to be precise).
In episode 4, Rockoon, in exasperation after having been constantly misidentified as a rodent, exclaims "Do I look like a lab rat?" His voice actor, Deven Mack Jr., played the character of Lab Rat in Grossology.
In addition, while taunting Nylocke's dramatic tone, Mack performs a voice similar to the one he uses to perform DotDotDot, complete with kinetic typography.
Apparently Michele Knotz is just as goofy and lighthearted as Kindarspirit when she's out of character.
Actor-Shared Background: The characters in TTA and TOME are all based on users from, the now defunct, TV Tome forums to an extent.
Audio Commentary: All of the Episodes have creator commentaries, which were originally posted to Soundcloud before being synched with the Episodes themselves and uploaded separately to Blip and YouTube. They all feature Chris Niosi himself, and often feature other members of the cast and crew.
Casting Gag: In episode 2, a character who is identified primarily as the sister of another character is introduced. She is the sister of none other than (the Real Life) Kirbopher, Alison Fanelli - also known as Ellen from The Adventures of Pete & Pete.
The Cast Showoff: Ravenfreak is a voice actor in-show, which provides an in-story reason for Lucien Dodge to perform a very impressive imitation of Swift's "Alpha" voice.
Celebrity Voice Actor: Unlike most of the rest of the cast, Jafari is not a voice actor by trade, though he was chosen because of the fake Noo Yawk accent he sometimes puts on in JonTron videos.
Contest Winner Cameo: Auctioned on Ebay. These are sold to fans to promote the show in some of the episodes, The winners send Niosi their own character designs which he TOME-ifies into something that fits the show. They then get inserted into certain scenes to appear near some of the recurring characters. A couple cameos even have brief speaking lines.
The Danza: Like his creator, the character Kirbopher's username is Kirbopher, and his real name is (probably) Christopher.
Harpo Does Something Funny: Mack gets to write his own dialogue for Rockoon. He even got to write a whole short starring Rockoon, titled Rockoon's Modern Strife.
I Knew It!: It turns out that Kirbopher and Zetto are controlled by the same player. This was a popular fan theory (just check out the WMG page for proof) which was finally confirmed in the season one finale.
Non-Singing Voice: Anna Kingsley, Flamegirl's voice actress, wasn't confident that her singing was strong enough to do the end credits song "Starlight Speedway" justice, and referred Niosi to her friend Leila Judeh who could match her Flamegirl voice for the song. Kingsley herself described Judeh as sounding "just like me but with a better singing voice".
Real-Life Relative: Chris Niosi and Alison Fanelli (who voices Splat) are brother and sister.
Averted, surprisingly enough. Even though the cast is filled with a roster of incredibly talented and versatile voice actors, each of them plays only one character. Or rather, one player - characters who are controlled by the same player share their voice actor. This was one of the earliest hints that Zetto and Kirbopher were one and the same - both were voiced by Chris Niosi. Zetto and SOFDTI were also credited as having been played by other actors than the ones who played Kirbopher and Gamecrazed respectively, before their respective reveals.
This promotional video. for Kirbopher's panel, premiering a new TOME episode at Kamicon, starts with Yami Yugi, introducing Kirbopher, and failing at pronouncing Kirbopher's name correctly. Then Nylocke drops in to try to help! Hilarity ensues.
Throw It In!: Nylocke interrupting his monologue about the Gemini Tournament in "Awaken the Beast" to confirm with GC that it involves pairs was actually Billany checking his line with Niosi as he was running through it, staying in character - Niosi enjoyed his reading so much that he put it into the finished episode.
A good amount of the casting was switched around before the project actually began. Although Nylocke was always going to be English in the remakenote He was an American in the original, though an Occidental Otaku, both Blake Swift and Casey Mongillo were considered for the part (presumably, Swift would have used his natural English accent rather than the Fake American one he ultimately used for Alpha). Martin Billany was actually considered for the role of Thorment, but Niosi decided to give him the role of Nylocke due to fitting the character so well (the role of Thorment eventually went to Harry Partridge). Jessi Nowack, who played Hyprelynx, was the first runner-up for the role of Flamegirl, and apparently only narrowly lost the part to Anna Kingsley. Other contenders for Flamegirl were Apphia Yu and Kira Buckland, both of whom got supporting parts later in the series as Whyti and Foreva. Finally, Neomutant was going to be played by Hans van Harken, but had to be replaced by Chris Guerrero at the last second because Harken became unavailable for the role.
TOME Season 2 was going to be a movie at some point, which would have began with the events of Episode 00 and led into the major events of season 2, included a mysterious new character who apparantly would have taken up Neomutant's role, and cut out the challenge of the Netkings. Chris Niosi decided not to go with the movie idea because it would have been too much of a balence between wrapping up TOME's story for viewers of season 1 and trying to appeal to new viewers who hadn't seen TOME and were only watching the movie, in addition to the fact that he wanted to have time to include the Challenge of the Netkings so as to go with the story idea he had in mind since the beginning. There was also a period of time in which the entire series was envisioned as a video game, an idea which came to pass in another continuity reboot after the project was over.
Concept Art reveals that Anidoug and Torben (who would have been renamed Torchure) were supposed to get updated counterparts in TOME like most important TTA characters, but were cut out because the episode they were going to appear in was scrapped. This concept art also reveals that Thorment would have had a more important role in this episode as Tormentros, and that Motherboard would have returned instead of SOFDTI (though still apparently in the dual identity of Gamecrazed). Rubirules also would have had a different final form called Graphix, which was cut because Rubirules's overall design had been overhauled and the form wouldn't work with his new appearance. Finally, some aspects of the world of TOME itself were reworked (the Sun and Moon concept replaced an earlier idea where Zetto's Netking room was the entrance to the hacker base, similarly to TTA).
Chris Niosi has revealed that Ruri was replaced by Kizuna late in development, after episodes 1 through 7 had already been completed. This was done because her entire disposition and personality were altered, and having Ruri as a cold and calculating hacker leader with a grudge against SOFDTI didn't seem to fit her.
Trivia for the TOME RPG Video Game:
Notable Original Music: The main four regions of the game's overworld have four different composers, to give each area a distinct feel. Kajmaster Kajet and The Living Tombstone return to compose the music for Edodes Woods and Telluria City, respectively, while Plasterbrain and Ccrusherp have been brought on to score Orange Island and Morganite Valley. Interestingly, the genders of these composers match the sexes of each region's respective Netking, since Rubirules has been given a Gender Flip.
Role Reprisal: Amazingly enough, almost all of the cast members from the Web Series return to portray their RPG counterparts. The few exceptions usually involve characters who have been given gender flips, such as in the cases of Sniperyda and Rulerruby.
Shout-Out: The Orange Island area is named after the Orange Islands from Pokémon's second season. On a more meta level, the area itself resembles the Rainbow Resort area of Kirby's Adventure, which was the name of the website that Kindarspirit's namesake was the admin of.
