Bad story, absolutely horrific endings and zero player influence on the course of the story. BSN going into meltdown and for once I agree.
lol You missed a few things, some decisions that matter:
THE GETH-QUARIAN RESOLUTION
First and foremost, peace between the Geth and the Quarians is impossible if you have not completed "Legion: A House Divided" in Mass Effect 2.
To achieve peace between the Geth and Quarians, you need to score between five and seven "points"; these points are rewarded to you as a result of your actions. As follows:
ME2: Tali: Treason: Mission incomplete: 0 points
ME2: Tali: Treason: Get Tali exiled: 0 points
ME2: Tali: Treason: Save Tali from getting exiled: 2 points
ME2: Legion: A House Divided: Rewrite the Geth: 0 points
ME2: Legion: A House Divided: Destroy the Geth: 2 points
ME2: Settle the dispute between Legion and Tali via Paragon or Renegade interrupt: 1 point
ME3: Save Admiral Koris on Rannoch: 1 point
ME3: Destroy the Geth squadron on Rannoch: 1 point
As you can see from the list, you can only earn two points in Mass Effect 3. It has been reported that whether or not anyone will even listen to you also depends on your Reputation; no specifics at this time.
THE GENOPHAGE RESOLUTION
Either Mordin or Wrex is slated to die in Mass Effect 3; you cannot save both. First and foremost, though: if you did not keep a copy of Maelon's data during "Mordin: Old Blood" in Mass Effect 2, it is impossible to save Eve. There are two resolutions to this conundrum:
Fake the Cure: if you have Mordin fake the cure, you will have to kill Wrex. This will result in the loss of Krogan support, which can be regained by persuading the new Krogan clan master that the cure is the real deal.
Create the Cure: if you have Mordin create the cure, he will die. This will result in the loss of Salarian support, which can be regained by saving the Salarian Councillor during the Citadel Coup.
THE GREYBOX RESOLUTION
During Mass Effect 3, the life of Kasumi and the fate of the Hanar homeworld lies in your hands; whether you can save both or just one depends on what you did with Keji's Greybox. If you let Kasumi keep it, you can save both; if not you will have to choose.
