- Ascended Meme: If the player tries to talk to Garrus when he has nothing to say in Mass Effect 2, hell ask Shepard to come back later as hes in the middle of some calibrations; as a result of Garrus having the fewest optional squadmate conversations, players heard this a lot. On top of the numerous jokes about Garrus fondness for calibrations in Mass Effect 3, the Legendary Edition renamed the display options as Calibration across the trilogy.
- Banned in China: For about two days in Singapore.
- Beam Me Up, Scotty!: Shepard never says "We'll bang, okay?" in-game. That quote originated from a Youtube Poop that mashed together several Shepard lines out of context.
- The Bechdel Test: The series passes with flying colors given that Gender Is No Object. Lampshaded in the "Citadel" DLC: FemShep and Miranda Lawson have a scene where they go out for drinks and decide maybe they need to be more feminine, only to both struggle to even string a complete sentence together on more stereotypically feminine topics.
- Canada, Eh?: Believe it or not, both Shepards Voice Actors are Canadian. While Jennifer Hale is fairly good at hiding the accent, Mark Meer tends to fall into saying "Aboot" every once and awhile.
- Cash Cow Franchise: Four novellas, two comics (plus two free mini-comics), and three spinoff iPhone games, so far.
- Celebrity Voice Actor: All over the place. Seth Green, Adam Baldwin, Yvonne Strahovski, Tricia Helfer, Martin Sheen, Claudia Black, Carrie-Anne Moss... the list goes on. In fact, it could be said that the in-development movie could very well be made with many of the characters literally being played by their voices.
- Channel Hop: Xbox Game Studios (then called Microsoft Game Studios) published the initial Xbox 360 version of the first game, but Electronic Arts published all subsequent entries in the franchise, starting with the first game's PC port.
- Character-Specific Pages:
- Doing It for the Art: BioWare had an entire animation team just for eyes.
- Fan Nickname: Pressly's known as "Hugs and Kisses Pressly" on the Mass Effect forums.
- Flip-Flop of God: After the launch of 8th generation consoles, fans began requests for an Updated Re-release of the Shepard trilogy, which Bioware remained silent on but EA confirmed would not be happening due to their lack of interest in remasters. The latter has since changed their mind on the subject with the release of Burnout Paradise remastered, and Bioware would then announce the "Mass Effect: Legendary Edition" in late 2020.
- Inspired by : Mass Effect's technological aesthetics, particularly of the omni-tools and Alliance armor, were heavily influenced by box office bomb Final Fantasy: The Spirits Within. The game's art director was a big fan of the movie's style.
- Long Runners: Fifteen years and counting, with four main games, eight episodic expansion packs,note two more-or-less independent multiplayer modes with their own mechanics and extensive unique content,note a remaster of the first three games, and two IOS spin-offs, with at least one more main game planned for some time after 2021.
- Missing Episode: The Pinnacle Station DLC, which was released with the original Xbox 360 and PC release, has not been included in the PS3 port or the Legendary Edition remaster for the PS4, Xbox One, and PC. The reason for this was due to the source code of the DLC being lost.
- Plays Great Ethnics: An inverse of the usual "White guy playing an ethnic dude," the caucasian Ashley is voiced by the black Kimberly Brooks.
- Relationship Voice Actor:
- Almost example, as Mark Meer (MaleShep) is married to Belinda Cornish, who voices Rana Thanoptis, the asari scientist who shows up on Virmire and has a minor role in the next two games. Don't forget that, in the first game, Shep has the option to ''shoot'' Rana. Turns out she was indoctrinated anyway.
- The series also has several Star Trek alumni voicing many characters: Matriarch Benezia is voiced by Marina Sirtis (Counselor Deanna Troi), the salarian councilor is voiced by Armin Shimerman (Quark), Gatatog Uvenk is voiced by Michael Dorn (Worf), Navigator Pressly is voiced by Dwight Schultz (Lieutenant Reginald Barclay), and Legion is voiced by D.C. Douglas (guest starring as Zepht in an episode of Star Trek: Enterprise).
- Female Shepard and Ashley are Thorn and Luna.
- Talking to Himself: All of the male elcor, vorcha, and hanar are voiced by MaleShep's voice actor, Mark Meer. This can result in multiple humorous exchanges where Mark is yelling back and forth at himself for an extended period of time.
- Taken Up to Eleven in the Blasto movie blip in the third game where every character is voiced by either Mark or Jennifer Hale, FemShep's voice actor.
- Teasing Creator: This bizarre tweet Bioware posted in January 2020. No context, just the intro of the first game.
- The Wiki Rule: The Mass Effect Wiki.
- What Could Have Been: Has its very own page.
- Writing by the Seat of Your Pants: Different interviews with writers across the series reveals that many things about the series' overall plot and some bits of lore was more or less constantly in flux and changed around quite a bit as members of the writing team were added or left (most notably the lead writer for the first Mass Effect, Drew Karpyshyn, left around half-way through the production of the second game and was replaced by Mac Walters). According to interviews in the interactive documentary about the third game, Final Hours, the (quite controversial) ending was not decided upon up until a few months before the game's release.
