For years, Mass EffectFan Fiction writers have used the idea of the male and female versions of Shepard being brother and sister as an excuse to include both in the story. For Andromeda, the developers themselves decided to use that idea so they could include both versions of Ryder.
Also in the case of Jaal, many fans expected him to be bisexual in the game and went as far as spread rumors about their perceived sexual orientation of the character, with support from the findings of dataminers. When the game actually came out, Jaal was indeed revealed to be a romance option but only for a female Ryder. The developers after listening to some feedback from fans, eventually decided to officially make Jaal bisexual and made him a romance option for a male Ryder when the game was updated by patch 1.08.
According to several Bioware artists who worked on the game and spoke to YouTuber Liam Robertson, upper management decided facial models and animations of human characters were to be completely outsourced to another EA studio, possibly EA Bucharest, because they did not see them as important enough to be done by the studio employees themselves. Bioware artists were not even allowed to polish the faces and animations done by the other studio in any way.
After the reveal that male and female Ryder are siblings and the N7 explorer is their father, the usage of the terms "Bro!Ryder", "Sis!Ryder", and "Ry!Dad", respectively, have become used in the fanbase.
Before (and to a lesser extent still after) her name was revealed, Peebee was referred to by fans as the "Raccoon" or "Hamburglar Asari" thanks to her distinctive dark streak across her eyes. Others call her Blue Shrek because of some similarities in the faces.
Doctor Lexi, the asari med bay officer, is modeled and voiced after actress Natalie Dorner, leading many of her fans to label her "Doctor Sexi".
The name of the new protagonist, Ryder, was essentially old news to the fanbase by the time it was confirmed at E3 2016, which had correctly guessed it from the dog tag found in the N7 Day teaser (which, incidentally, does notbelong to the protagonist, but likely their father Alec Ryder).
A lot of people correctly guessed that Liam was going to be a love interest despite no information regarding him as such.
The Premium edition, which included costumes, gear, and a pet monkey for the single player campaign.
The Premium Plus edition, which contained everything in the Premium edition plus a pile of multiplayer equipment loot boxes.
The one that became famous, though, was the Collector's Edition which included a remote control toy copy of the vehicle from the game, a steel game box, and no game. What was intended by the title was that it was a collector's edition of the model, but this was in no way obvious from the ad copy that listed "Mass Effect Andromeda Collector's Edition" in big letters and then "Diecast/Remote Control Nomad ND 1" in a different font below that.
Meaningful Release Date: Unintentionally. The game is being released in North America on March 21, 2017, which reads as "3/21" on American calendars. BioWare Director Aaryn Flynn has said the developers didn't even realize the significance of the release date until fans pointed it out to them.note The significance being that the date is jokingly referred to as "3, 2, 1... (launch!)", which fits the game's space theme.
Kumail Nanjiani, the voice of Jarun Tann, has said that playing the first three games was his favorite gaming experience.
The entire idea behind the "Explorers Wanted" contest, in which fans got to submit auditions to Bioware with the winners being selected to voice minor characters in the game. Cari Sholtens and Kyle Land won respectively.
The game was passed on to B-team Bioware Montreal as the main studio at Edmonton wanted to develop Anthem. The Montreal team was given very little instructions for the game outside of the edict that it would not touch upon the conclusion of Mass Effect 3, but also couldn't use the Frostbite Engine's modifications they used to develop Dragon Age: Inquisition as Andromeda was made using a newer version of the engine, forcing them to develop the RPG mechanics and animations from scratch.
Even though the game started development sometime before Dragon Age: Inquisition finished production in 2014, the team loss 2 years of development trying to create a system that generated fully functioning planets for players to explore but no engine or program could deliver satisfying result in the Frostbite Engine, forcing them to go back hand-crafted planets.
The game was far from finished by 2016, with incomplete assets, broken animations and cutscenes, causing management to panic, this led to EA to assign some lesser studios in Eastern Europe and Asia to help with development, with one studio being assigned to develop the facial animations while Criterion Games helped with the vehicle mechanics. This ended up causing problems down the line as communication between the studios was chaotic at best and non-existent at worst. The fickle nature of the Frostbite Engine ended up slowing development due to constant bugs and glitches popping up over the smallest changes and they couldn't get any assistance from people with knowledge of Frostbite's code as most were assigned to work on EA's sport titles. This caused EA to delay the game to March 2017.
Most in-universe characters joined the Andromeda Initiative eager to explore new worlds in a new galaxy, much like the original intended No Man's Sky-syle planet generator for players to explore.
Then the characters hit disaster on arrival and find the worlds uninhabitable, much like how the developers struggled to make the randomly generating planets fun to play for over two years until they finally had to admit it wasn't working near the intended release date.
Then the characters had to scramble together makeshift infrastructure from what little resources they brought with them, and try to make livable worlds from the uninhabitable and hostile terrains... Much like how the devs had to scramble together a narratively cohesive story and fun terrains from what was left of their experimental game, with the notoriously difficult-to-work-with Frostbite Engine.
The story is largely about fostering cooperation between bickering and scattered factions to make the disastrous Andromeda Initiative a success... Much like how various BioWare and outsourced Eastern European and Asian studios had to try to make Mass Effect Andromeda a success, with communication between the various studios being chaotic to nonexistent.
Most characters are inexperienced or under-qualified workmen trying to scramble together livable worlds due to most Andromeda Initiative leaders being dead, missing, or absent... much how BioWare struggled to make Andromedia a success (with the notoriously difficult Frostbite Engine) with little to no help from upper management.
In-universe, Pathfinder Ryder is seen as a poor substitute for their father, the far more experienced and beloved previous leader... Much like how the devs anticipated Pathfinder Ryder being seen as a poor substitute to the more experienced and beloved Commander Shepard in the eyes of many Mass Effect fans.
The two voice actors for the Ryder siblings (Tom Taylorson and Fryda Wolff) previously played two other characters with a familial relationship in a video game: Octodad and his daughter Stacy. Subtly referenced in this promo video where Fryda looks at Tom in the recording booth and makes "blub blub blub" sounds. It's the only sound Octodad ever makes.
The original design of the game called for a Procedural Generation system for planets similar to No Man's Sky. Numerous technical and engine difficulties forced the system to be cut and the final game features hand-made environments.
According to the writers of the game, several alien species were cut due to a mix of budget constraints and visual designs that were not conductive to cosplaying.
Word of Gay: The update patch 1.08 revealed that Jaal is bisexual even though he was originally only available for a female Ryder. The use of this trope on Jaal was suggested by fans and eventually made canon by the game developers.
