What happened to mass relays taking out entire systems when they're destroyed? Remember Arrival? Shit killed most of the Batarians. Oh wait. ME3 plotarmor lul.
LOL. He speaks the truth, blowing up every relay in the galaxy is gonna cause some shit.
Seriously, right up to the kid, the game is a tight as it's gonna get - even if you accidentally fuck over the Quarians because you 'didnt know'. BioWare said you'd be able to increase your success at the end, just like the other ME's, but they should have said 'reduce your degree of failure'.
After solving several galactic confrontations, some of them involving AI, choosing to wipe out synthetics/become the Illusive man and take the reapers/everybody becomes The Illusive Man through dna, oh and destroying the Relay system are not choices Shepard would make. Anderson even says "There's always another way..." in the TIM confrontation, just before he makes you shoot him. Was it a foreshadowing? That Shepard could find an equitable solution where TIM succumbed to his desire to strengthen humanity?
You spend the whole game fighting fate (and if you get the really good endings -
successfully fighting fate, I might add), only to submit to it at the end. If the kid is the form the reapers chose to talk to me, I don't want anything to do with him or his fucked up options. The Shepard of the other 99% of Mass Effect would find another way.
