I don't recall anything like that but in order to save both the Quarians and the Geth, you had to pretty much play ME2 at the very least and do both Legion's and Tali's loyalty missions and successfully resolve the argument between them when both loyalty missions were done. That requires quite a bit of renegade or paragon points and play time.
I think a good example of trying to save everyone without any consequences is in DA:O where you can do Redcliff first and then go to the Circle to get mages to help save Conner and still complete the Circle of Magi quest without any consequences at Redcliff for taking too much time to complete the Circle of Magi.
Yes it was hard to get but it didn't mean it wasn't the RIGHT choice. making every other choice the bad one, taking all moral ambiguity away from that instance.
Giving a peace option unless it comes with massive consequence will ultimately harm that experience taking away all tough decision making process. Like how can you have two choices which are supposed to be incredibly hard where you have to weigh out who is in the right and wrong, protection vs freedom, etc etc. but then have a choice which throws all of that away so you can save both sides without losing anything. otherwise the choice is made up already, instead of a choice of opinion and own feelings like how it was for the Quarian Geth war before i knew i could save both of them.
The Krogan and Slarian was a wonderful aspect no matter what you didn't win, two ways Mordin died and only one way he lives and yet the Krogan still go extinct. that choice is completely a hard choice. Making a way so you get both sides with no major loss only makes a good, and bad choices. Unlike the one at the end of DA2, wasn't the best ending but people argue who was in the right, and who was in the wrong, who deserves your support more. there wasn't some magical way to save them both.
