I enjoyed it, but I can't work out whether the jab at ME3 "Retakers" is snide or light hearted. In any case, I don't have any right to ask you to alter the endings I found, for three reasons:
You didn't advertise or promise me anything,
Even if you had, I didn't pay you anything,
There were no technical storytelling errors that I could detect. No plot holes, and you didn't shit on your threads or the lore. The difference between making those mistakes and not making them is the difference between having any artistic integrity to defend and not.
I didn't like all the endings. I wanted to be able to do more at the *other* planet the human can go to earlier on... But even so, I can stand by them all as artistic decisions, unlike ME3's actual ending.
Edit: I might have found one error, just skimming. Don't elcor move slowly regardless of the gravity? To paraphrase the in-game encyclopaedia, "a consequence of developing on a planet with gravity so high that a single misstep can mean death".
Ah, still, this is essentially fanfiction, and not subject to the same checks and balances that professional, multimillion dollar products ought to be. It doesn't matter.
