Casey Hudson, the project lead of Mass Effect, was a huge Deus Ex fan, and I honestly think he just got so hyped up on it that he injected Deus Ex into Mass Effect. The thing was, it didn't fucking fit.
I spend all of Mass Effect 3 getting the quarians and the geth to make peace, sacrifice along the way to get it, lose Legion after he just discovers first person pronouns (sob) and this fucking hologram child (why does he look like the kid on Earth from the beginning of game 3?? are the Reapers pulling the image from my mind?? am I already indoctrininated?? NEVER EXPLAINED) appears out of nowhere and says that organic and synthetic life will wipe each other out AS AN INEVITABILITY and the super genius solution has been genocide every 50,000 years, then rinse, repeat, reset factory settings. Now choose red blue or green!
No. I don't agree with the fucking problem. I don't think organic and synthetic life are going to wipe each other out this time. I've made progress. Does that mean nothing all the sudden just because holobrat appeared? I'm sure as fuck not willing to put all organic life in the cyborg blender, become a Reaper, or destroy galactic travel in order to solve the hologram child's nothingburger of a problem.
And none of this explains why the Reapers were so mustache-twirling evil the whole series?? Listen to Harbinger and Sovereign talk, they're Voldemort in giant squid form. I was expecting an evil plot, not that they were just galactic Roombas made by another race. Why did they make their Roombas so evil?? If there's no evil behind the curtain, why evil curtains? Why--WHY--
I was so hyped to find out why sentient robots were wiping out civilization every 50 millennia, and it turns out, it was to keep civilization from being wiped out by robots! OH HOW NICE, THAT MAKES SENSE.
