And that's just the problem. Do you mean the Canon-Destroy galaxy or the Endings-Homogenized-to-Meaninglessness galaxy? Because I didn't help create either of those and I want them to respect choice more, not less. You're asking for Shepard's Legacy. You want to explore the post-Shepard's choice galaxy. Tough. That's not what Bioware's been advertising. "New" has been their buzz word.
I hate the idea of a reboot. On the contrary, I see Ark Theory as the only path to any sort of narrative continuation for the franchise that respects player choice.
As I see it, respecting a player's choice means presenting a game world where the effects of that choice are evident and apparent. A game world wherein those choices simply do not matter, like a GNOCA (galaxy no one cares about,) does not respect that choice, it avoids it.
It is possible to create a game that respects most of the player's previous choices, including the fate of the Geth, Quarians, Krogan, and Rachni, but only at the expense of respecting the final choice between red, blue, green, or black (I think refuse should be called the black ending to keep the terms consistent.) If you design a game that respects the space magic color choice, however, you sacrifice your ability to significantly respect most of the choices that came before it. That is, after all, one of the big reasons given for loathing the space magic ending in the first place.
That damage has been done. It simply isn't possible to respect everything that has gone before, but that's no reason to throw the baby out with the bathwater, even if there is a turd floating in the tub. The decisions you made as Shepard were made to texture a fictional setting that you cared about. To respect the spirit of those choices is to preserve that setting, even if it means disregarding the specific choice you might have made at the time.
