I see well as far as rachni they were indoctrinated during "the war" and so assuming you let them live I think they'd be fine.We got the immediate impact. I'm just wondering did the krogan or rachni try to go to war, did geth/quarian stay peaceful, what was grunts purpose, what happened to shep if yours lived? I was kind of expecting epiloge like in dragon age origins where they went into detail of all your choices and how they effected everything in future
I guess the game didn't really spell it out and I thought they would just like a paragraph say depending on whether eve was alive or not saying whether the krogans tried to expand or not but I do think some things are heavily inferred
