You didn't read what I wrote.
I didn't understand the game? The potential you talk about is just several endings, good and bad endings, exactly what the developers didn't want because it goes against their own work, the idea of the ending. Maybe understanding the game means under-stand the game to see its own writing instead of ignoring what is written and basing criticism on expectations.
And that potential I described could have been amazing. No two endings identical. Some where Shepard lived and is hailed as a hero. Others where Shepard lived but whose name was cursed for millenia. Some where Shepard was a saint, a god-king. A soldier for the Alliance, a Spectre, a hermit, an ambassador, a new Illusive Man (or Woman)
And the galaxy could have been shaped in so many different ways: fragmented by the loss of relays, plunged into a new dark age. Or united, both organic and synthetic, by their shared experience in fighting the Reapers, not needing their DNA rewritten. Or they could have turned on each other once the Reapers were dealt with. The Reapers could have been destroyed, or enslaved, or freed, or simply left.
I understand that the game gave me hundreds of choices (perhaps more) over three games. We were shaping a story, not being told how it's supposed to go.
And every freaking one of these shapes led to Shepard burning in the end, with exactly one outcome hinting that Shepard may live.
Different choices should lead to different results. Good. Bad. Okay. Meh. Otherwise why are we given choices?
IF their message was "Life sucks. Then you die" Message received. But I'd like to think the Bioware writers have a less grim outlook on life, or at least leave such baggage at home next time.
