The Shadow Broker, Donovan Hock and The Cerberus any possible connenction with the Andromeda Initiat

Did your translator glitch or something? I don't recall ever saying they should mash the endings together into some unrecognizable blob of bad writing. On the contrary, I suggested they should leave out the details and just go with "Shepard defeated the Reapers with the Crucible. The End."

Considering the sequel doesn't even import ME3 saves I don't know why the endings should be in any way relevant to how they continue the franchise.

The TRON lines are easy to deal with. You can just explain that after a while they faded away, leaving no visible signs of Synthesis. 

I was just addressing the TRON lines specifically. Those are easy to explain away. 
Though Synthesis as a whole was left pretty vague, with the Extended Cut looking towards what may be possible compared to what is reality, so I think there is plenty of wiggle room for good writers. 

The TRON lines were short hand. The problem is synthesis is so out of left field and so divergent from anything else you can't possibly bridge the gap. Either everyone is some weird transcendent new thing in which case they certainly wouldn't act like they did before or they're not. And even if they do act recognizably, there's no way such a massive change would be relegated to one offhand mention.

"Yeah all life in the galaxy got its DNA blended together. No biggie. Anyway, about that genophage...." - not gonna happen.

So is refuse, for other more obvious reasons. It's a middle finger to the players, sure but technically it's a legit ending. Got its own space grandma and everything.

Err, no. That would be disregarding the endings which at this point no one wants. Well, no one except people who expect Bioware to personally apologize to them. Not to mention negating the biggest choice (no matter how dumb the setup) of the whole series.

It's like some of these people had to outright spit the "Ai" word at Shepard's face despite how nonsensical it would be in the context of their encounter.

"I've shot a man before, why wouldn't I shoot another?"

There's your answer.

This isn't just some historical event- this is all life in the galaxy fundamentally changing. There is simply no glossing over this fact. There is no portrayal that is compatible with both destroy/control and synthesis. Right after the change everyone would be exploring it, discussing it, whatever. As time goes on and they adapt to it (assuming adaptation isn't instant) technology, society, everything would skyrocket in a wildly divirging path. The rate of advancement would be astronomical compared to the galaxy in Destroy/Control. Twenty, even ten years down the road, the galaxy would be unrecognizable from what it was. That's what it would mean to properly portray the effects of this ending. To not do so is essentially to disregard it.

Personally I think they should've allowed a dead Shepard import from ME2. Make the character you create in ME3 have a different name, or only ever be referred to by his rank (no need for anything else since no relationships would carry through), and go off a slightly worse than default playthrough with all expendable squadmates dead, the VS joining Hackett regardless and a few human token squadmates making up the difference so you have a full squad, with romance maybe being possible with only those people. Joker goes back to sullen and kinda dickish. It actually makes a lot more sense than Shepard- the notShepard is just an alliance grunt, no space Jesus or Spectre powers to bring into question why he's just an errand boy, no bullshit useless incarceration, it's justified why we're back to begging the council for help for Earth, FailLeng would actually be a threat (well, not gameplay wise but you know what I mean). But I digress. Dead Shepard was invalidated by ME3 but Refuse has yet to be invalidated by anything. I don't think it should either, anymore than any other ending. Precedent does not imply necessity.

Codex Entry: Commander Shepard "The First Human Spectre" is a fictional character and the subject of several interactive films published by Tethras Enterprises. These films were wildly popular due at least in part to the player being able to customize Shepard, from gender to appearance. Shepard could even have romances with several of the colorful cast of characters. The viewer was able to experience the adventures using Shepard as an avatar, making choices for Shepard and customizing the story to suit individual tastes

Over its five year run, numerous adventures where made available for Shepard's fans to experience. Though the central plot involved foiling the "Reapers" a mythological race of sentient AIs the films credited for the extinction of the Protheans.

Shepard's run ended with the so-called "Shepard Incident". The conclusion of the final film was considered so controversial that it caused an unprecedented uproar which even a rereleased ending could not quell.

Currently Tethras Enterprises has no plans to bring back Shepard for other stories. However, they are looking into the licensing Blasto for a new series.

I've never particularly disagreed with any of your issues with this game or with the way BioWare handled Mass Effect 3. I experienced that whole thing, also. They should've handled that situation better in 2012. I disagree that they still owe us a "my bad", now. It's nearly 2017. A fresh start will be good for everyone in many respects, not only in regard to the game.

Maybe you have no faith left in BioWare. I can understand. Something keeps you coming here everyday, though. You clearly still have a passion for Mass Effect. I think people just have a hard time reconciling this passion with the unrelenting skepticism. At some point, one or the other will win out, I guess. I hope you enjoy the game. I hate to see the franchise ruined for you.

I come back because Bioware used to be great. And DAI, despite its flaws, was a decent-to-pretty-good game. And I'm curious about the mysterious third IP.

But Mass Effect? They burned me too many times to trust them with that IP again. Not without CONCRETE proof that it's worth returning too. "You haven't played it yet" is not a good enough reason to trust that somehow they've managed to turn a corner. With ME3 I went in with pretty low expectations and was still bitterly disappointed. This time, I'm going in assuming the worst, and maybe this time I'll be pleasantly surprised.

My Shepard didn't matter. ME3 made that abundantly clear. And you said yourself, they're not going to change it now.

So yeah, I'd rather he never existed to begin with than have him hijacked by "Art".
