Transcendent Humanity by Solaris242 reviews

Humanity never developed FTL. The Prothean archives contained no technology, no Element Zero, just a warning. Isolated from the rest of the galaxy for two thousand years, restricted to their only system, how will humanity have changed when they first meet the Turians? AU, alternate history of humanity and First Contact.

Interesting Times by Zanarkand Kido reviews

Coming to terms with being reborn? Doable. Finding out you're in the Mass Effect universe? Slightly more difficult. I know I'm no soldier material but I want to do what I can to help save the galaxy. To that goal I will become one of the worst beings in human society. A businessman and politician. A SI/OC-story of a different kind.

On the Illusion of Might by evevee reviews

We thought ourselves powerful, able to conquer a galaxy with nothing but toys. When we overcame every challenge, breached the space between the galaxies themselves, what use were the words of a race ashamed of their own past? Yet we cannot deny that we were warned, for while a challenge to a human is laughable, a challenge to humanity is a death sentence.

The Fourth Council Race by Knight Vigilant Koren reviews

A few minor and realistic changes in the decisions made by the leaders of humanity drastically altered the path of Citadel Space and the Reaper War. This is the story of caution and planning over recklessness, the path of the juggernaut over the glass cannon. This is the story of humanity as it should have been. A power worthy of its Council seat, and one the Reapers can't ignore.

Mass Effect: A Very Terran (Re)solution by NihilMomentum reviews

What would happen if someone with vast knowledge about the Mass Effect Universe, both official (wiki/Codex) and theoretical (fanfics), decent fighting ability and a plan was dropped into that Universe 13 years before Eden Prime? As it turns out, quite a lot! FemShep. Soft HFY. And a very different kind of self-insert. [The story will be revised after the First Act is finished]

Mass Effect: The First War by ProfFartBurger reviews

The Prothean Ruins weren't. They contained little more than mentionings of an Alien Society; as a result, humanity develops on a completely different path than what was intended, and when first contact is made not with the Turians, but a desperate, destitute race viewed as beggars and thieves, how will this dying race change Humanity? And how will Humanity change the Galaxy? *A/U!*
