* ActorAllusion:
** In 3.5 ''Application'd'', Zaboo can be seen wearing a ''[[http://www.effinfunny.com/legend-store?id=1 Legend of Neil]]'' shirt. ''WebVideo/TheLegendOfNeil'' is another web series, created by Zaboo's actor, Sandeep Parikh.
** There are at least two ''[[WebVideo/DoctorHorriblesSingAlongBlog Dr. Horrible]]'' references: Riley calling Zaboo "Bad Horse," and Codex putting up her fists while referring to "hammers." Also, Codex owns a frozen yogurt maker; in the musical, froyo was an important symbol for Penny and Billy's relationship.
* ActingForTwo: Tink's twin sisters Tara and Lara were originally supposed to be played by twin actresses, but due to a scheduling snafu, they had to hire one of the extras to play both parts. And she had no acting experience.
* TheCastShowoff: Felicia's fond of writing actor's talents into the script. Bladezz is a talented card dealer because actor Vincent knows sleight of hand card tricks, Codex plays the violin as does Felicia Day, Tink plays basketball, and Amy Okuda shows off her dancing skills in the music videos. Also stuntman Wade Wei was played by an actual stuntman who did his own stuntwork. Felicia and Vince also show off their impressive vocal talents in the music videos (namely, Felicia singing and Vince holding a Bollywood-style note with perfection).
* DVDCommentary: Each season was compiled into its own Youtube video and added "trivia annotations" written by Felicia Day about the development of the show.
* OneOfUs:
** Creator/FeliciaDay definitely knows what she's writing about. Even people who don't play games but spend a lot of time online will recognize the character types.
** And we don't even need to talk about Creator/WilWheaton and his massive geekitude.
