WARNING: Spoilers about ME:3's ending. If you have been in a hermit's cave and *somehow* do not know, or wish to know, details about the ending of ME3, then do not read this. Kthxbye.
If ME: Andromeda underperforms, they won't be inspired to fix *anything* because they'll be in the red and corporations are NOT here to make us happy. They're here to make money, and while that *should* include making us happy, there's no lack of crap on the market proving customer satisfaction is not 100% required. Once you come to understand that every product put on the market these days is put out there at. a. loss. ... and that the ONLY way a company has to survive putting out the product at all (even if it happens to NOT please the consumer base) is to sell enough of it to break even, you will understand why "We won't buy Y till you fix X" will never...ever...work as a tactic.
Most games today *barely* make a profit even when they do well in first release. They wouldn't have the cash on hand to "code up a DLC" (OMG the ignorance of time, manpower, and overhead in that statement makes my teeth itch) to do *anything* for ME3 (or any other part of the franchise). If ME: Andromeda "underperforms," it. will. kill. the. franchise. The sheer length of time between ME1 and ME: Andromeda makes this a dangerous venture. There are folks playing games like this now who weren't old enough to use a bleeping mouse when the franchise started. This newest release, kinda like WoW (which has degenerated into a sad shell of a once decent franchise and pretty solid MMO), depends *entirely* on the loyalty of the original player base PLUS the hopes of pulling in fresh blood (for example, some of my kids are now old enough to play the franchise...God I feel old typing that).
The thing about changing the ending...again...is...at some point you're bucking heads with the Writers. SOMEBODY (probably several members on the team) actually *liked* the ending, or it wouldn't exist. It went through concept, script, storyboarding, hand animations, code-time estimations, how-the-heck-do-we-make-it-PLAYABLE? testing, and a dozen other things. I think they should have had a chat with the developers of Fable, Final Fantasy, and (of all things) Alpha Protocol about how to make choices in a game *really* matter....but in the end, I suspect the problem with the ME3 ending was that everyone writing the ending was focusing on the fact that one way or another you were *supposed* to confront/battle the reapers in the "war to end all wars" - what they missed was that what we all WANTED (aside from an option NOT to kill our character that we'd invested literal YEARS into playing) was the ability to experience the world after the war.
If they left the ending AS-IS (with the four...not three...options, come on, am I the ONLY person who just pops a cap in that walking acid trip brat?!?)and gave us a way to experience the *result* of our choices, I think that would make up for the mess. And they could do *that* in four brief vignettes at the start of ME: Andromeda....

We already begged for a fix. We got the DLC, which added the "Ok only Shepherd has to die....if becoming "one" with the Reapers is death" Synth option, and the shoot the starchild option (which I think may be the single coolest ending of the four, because it's the only one that leaves OPEN the question of the Reapers for another whole 50,000 years worth of story in the ME universe and what happened since nearly *all* of the main races of the ME franchise would have been wiped out by the Reapers).
Rather than go back and try to fix ME3's ending...again...the Developers should made VERY certain that the ending you pick and all the major choices along the way*severely* affects the look, feel, even available races...of gameplay for ME: Andromeda and it's (I hope eventual) DLC.
