Well done. Very thorough examination of both Xeno/Assimilate parties.

There could be a little more organization, but you followed chronologically, which necessitated the extra setups. As an example, the technology curve could've been collected in a single chapter (ME1-ME3), but that would've broken the sequence.

A bit of disagreement on the Suicide Mission having a minimum required death count. In my opinion, there should be a chance of survival, perhaps similar to XCOM's RNG setup. Weight it heavily against survival, but make it possible. For the most part, this would be a story-driven requirement. If Butcher is directing the operation, higher chance of fatalities. Hero would have a higher likelihood of survival. Purchasing equipment for individuals would affect the weight as well, along with Normandy upgrades.

Again, not giving characters plot armor, but buffing the odds.

Great work!

I think I need a bit more context here
What races can give legitimacy points?
How much combat proficiency necessary to take earth and its concequences?
Is it possible to play with an asimillation counsil and a xenonationalism aliance based on shepards prior choices?

At every turn its always the Aliens did damage but they can never achieve any serious damage no crippling blows humanity always comes out the other side stronger because even though this was supposed to be a story of an oppressed people who fight tooth and nail for everything they have they always seem to have the end make the cost worth it there is no Pyrrhic Victory for Humanity never do they say was it worth it no it seems Pyrrhic victories are reserved for the enemy I came into this believing Humanity would be like the Helghast in Killzone they are true "Renegades".

the Minor Races in ME are only Minor because they have no need for stronger militaries if a threat was around to cause them concern they could easily create a strong military and no the Volus would never leave the Turians.

Yeah the Batarians would be a bigger problem than you are letting on they would be going full guerilla warfare and what happened to the Batarian Homeworld Nation States they would have been difficult to pacify and would have used WMDs during the end of the war and with the Batarian infrastructure destroyed it would bankrupt the Alliance to feed and care for all of these Batarians not to mention that human soldiers would be dying by the dozens each day trying to police them but who cares about a few dead clones right?

You like to reach conclusions without providing a valid reason for why something is happening and you are making the Humans the only competent government in the Galaxy the Batarians for ignorant arrogant and stupid and the Council is weak and ineffectual why is this? the Turians honored an agreement with the Batarians to defend the Homeworld the Turians have the most advanced force in the galaxy yet Humanity which was burnt out from fighting was able to defeat the Batarians and the Turians that's called Bullshit and you say the Hegemony somehow disappeared how is that the High Command would have evacuated before Human forces attacked their bunker and at least would have sought safety with the Turians and later would lead the Free Batarian states as the Hegemony and after the Turians fought and died for the Batarians they wouldn't just hand over the territory to the enemy nor would the Council allow Humanity to rule the Batarians without ensuring Batarians certain rights to protect them you are distorting the the Council they are peacekeepers and ensure prosperity for everyone they wouldnt throw away a whole species especially a species that was as important as the Batarians .

I would like to note that the Council races have not mass but at least bulk Cloning as observed in ME1 and 2.

Also you don't seem to understand the speed of ME ships which can go 10-15 light years a day for reference Alph Centauri the closest system to Sol is 4 light years away which would make that trip a few hours.

This story is shit there is no way Humanity could maintain this level of warfare for so long nor could it transport arm and armor millions of clones maybe if you had said that they use mass armies of clones but the disadvantage of the clones was they weren't armored and were just given guns because nobody cared if the clones survived this I could ignore but not this shit the Council would never stand by as a member species which was being considered for Council status be destroyed by a hostile species but thats beside the point of Humanity could not destroy the Batarians in ME1 it was doubtful Humanity could win a war against the Batarians you keep giving Humanity ships that magically appear out of nowhere where were they manufactured how long does it take to manufacture why don't the Batarians have more ships in production where are the orbital defenses any every species would have orbital defenses in the form of space stations like Halo Mac Canons around Earth and Reach in Mass Effect they would have them defending their planets and moons and especially the Mass Relays fortifying the choke points. Once the Turians join the war Humnity doesn't stand a chance the Turians have the strongest army in the Galaxy and thats during peace time. Your understanding of military tactics is lacking in ME their ships travel in real space as opposed to Halo where they travel in a different dimension this means you could have "listening posts" to keep watch over any ships approaching a system and if the Human 5th fleet travelled through the mass relays to attack the Batarian colonies then the Colony could send a distress signal and a Batarian fleet would be there within minutes to help cutting off the relay as an escape route and there is just to much to go into like how the Council would not forgive a species that is commiting crimes against civilians of all species attacking ships and colonies of all species this of course includes Council member species. Oh and you treat the Batarians as some primitive species who have no concept of the galaxy beyond their territory or the fact that a hostile species is attacking them saying that the Batarian Nation States on their homeworld start attacking each other during a planetary invasion is bad writing that would be like each state in America attacking each other after Russia destroyed the Navy and Air Force this would not happen nothing unites a people more than a common enemy.

I designed this ship because of this story. Your right, it does make you rage.

I have a hard time believing that the Turian Hierarchy would defend the Batarians in this situation. Do they know the truth or are they believing what the Hegemony said? If the Turians had been attacked in the same way as Humanity, they would have exterminated the Batarians. The Humanity you have portrayed so far would never accept that armistice. Wtf.

FYI, it should be Intragalactic or Interstellar. Intergalactic means within more than one galaxy.

why did humanity decide to join the bloody council of all things, it is the most ineffective government i've ever seen in a video game and the humans are really limiting themselves by agreeing to the citadel treaties, humanity basically just took a fucking knife and neutered themselves! Kill all the filthy alien scum!

I think that you have perhaps underestimated the play of terror in the negotiations with this council. One cobalt enriched tsar bomba functionally ruins the planet forever. I doubt space going species that know each other's home address should wish to chance such a thing.

I don't know why you insist on making every other species hilariously evil.

This is a damn good story so far, and I've only scratched the surface. I really lool forward to the reat of the story as a whole. Unfortunately I require sleep... damn human body needing to recharge.

There is no real reason for humans to sign that treaty and give up their advantages and join the council they are not economically tied to the citadel in any way and the citadel races have shown time and time again a reluctance to fight wars
