History Roleplay / MassEffectAlteredHumanity

** [[spoiler:The Keepers in canon were a SlaveRace, modified by the Reapers to maintain

* AdaptedOut: While some absences can be justified due to the ForWantOfANail nature of the quest (such as the Geth and the Reapers), others are just unexplained. [[BotanicalAbomination The Thorian]] never makes an appearance and [[LastOfHisKind Javik]] is completely unaccounted for despite Humanity having been on Eden Prime and poking at the ruins found there for ''millennia''. And while the Raloi get the above AdaptationExpansion treatment, the also AllThereInTheManual mentioned Virtual Aliens just never appear.

* PoweredArmor: The Dominion's "Gorilla" Heavy Exosuit, which allows infantry to use heavy weapons that would normally be restricted to vehicle mounts while still allowing Dominion soldiers mobility, and much later on their "Brute" Heavy Combat Exosuit. The Elcor take this UpToEleven with their own version that turns normal soldiers into walking tanks.

* WorthyOpponent: The Krogan definitely consider the Turians and Humans to be this. [[spoiler: [[KillThemAll It doesn't end well for the Krogan.]]]]

* FamousLastWords: "I still can’t believe my granddaughter became a ''marine''." [[spoiler:Fleet Admiral Williams]]

* ColdWar: After making first contact with the Dominion, the Turian Hierarchy and Colonial Alliance fell into this. The conflict had officially ended after the Foundation War, as both factions had become allies along side the Terran Dominion after nearly two centuries of fighting against the Krogan.

*** [[spoiler:EDI is around as a Spirit from the Colonial Alliance rather than a Human VI upgraded to an AI by Cerberus like in canon. In fact,her name here is "Edi", which is short for "Edinihiah" - a Raloi historical figure.]]

* GreatBigLibraryOfEverything: [[spoiler:The Archive/Citadel is covered in monuments that contains the sum of every star-faring species since the beginning of the Experiment's deeds, culture, and history. Though the vast majority of their technical knowledge has been erased to ensure whoever claims the Archive cannot destroy yourselves and will continue to develop along their own path.]]

* DrivenToSuicide [[spoiler: Stellar Generation Prime is on the verge of mass suicide after millions of years of races in the Milky Way constantly failing their Experiment.]]

** AbusivePrecursors: [[spoiler:The Tribulations they unleash on species for their Experiment have driven ''thousands'' of sapiant, space-faring races to extinction. WordOfGod says they do this Experiment partly out of entertainment and even goes as far as to compared them to a KillerGameMaster. Somewhat {{Downplayed}} as they aren't actively looking to drive races to extinction and actually want a race to compete their Experiment, it is just very difficult to do so.]]

* {{Precursors}}: [[spoiler:Stellar Generation Prime]]

* RivalsTeamUp: Rival faction, the Turian Hierarchy and the Colonial Alliance, team up to fight the Krogan Clans during the Foundation War.

* AbusivePrecursors: [[spoiler: Stellar Generation Prime. To end their stagnation and boredom they've been subjecting the Local galactic cluster to waves of constantly escalating galactic disasters in hopes that a generation will survive them all and surpass their own power. No one has ever succeeded, and they've been doing it for ''billions'' of years.]]

** Subverted with the Terran Dominion, due to their culture they could care less about alien art.

* FinalBoss: [[spoiler:The Keepers of the Archive.]]

** [[The same applies to what is beyond the Alpha Relay. Instead of an archive it is a hub for the Relays, allowing anyone who possesses it the ability to travel to any relay throughout the galaxy. And like the Archive it is protected by their own End Game gaurdians.]]

** [[spoiler:According to WordOfGod, the same applies to what is beyond the Alpha Relay. Instead of an archive it is a superweapon, and like the Archive it is protected by their own End Game gaurdians.]]

*** [[spoiler:EDI is also around, being a Spirit from the Colonial Alliance rather than a Human VI upgraded to an AI by Cerberus like in canon. In fact,her name here is "Edi", which is short for "Edinihiah", a Raloi historical figure.]]

** Despite the earlier start, various canon characters start appearing when the galaxy reaches the canon start of the series.

* FictionalSport: The Triumvirate have a combat simulation sport ({=SimCom=} for short). It was created by the Colonial Alliance by basing it on the combat simulation that are taught as basic education in the Terran Dominion. It is quite popular within the Triumvirate, with professional teams from both the Alliance and the Hierarchy. The Dominion doesn't have any professional teams, and human players in these sports leagues are doing it more as a hobby than anything. [[spoiler: And the Yahg fell in love with it the moment they heard about it, and compete heavily in every league they are allowed to participate in.]] In other non-Triumvirate factions it is moderately popular, mostly thanks to Colonial Alliance marketing.
