"... on one of the golden worlds our long-range sensors have identified in Andromeda's Helius cluste

Plausibility is irrelevant.  Consistency is.

So, now plausibility is irrelevant? Wow. Also, you don't know how things will evolve, new lore can be a thing. 

Well, maybe we just need to give this new-ish lore some time to breathe. Like fine wine...

Alot of people really enjoy that aspect of lore. The nuts and bolts of the universe. So, they both want and need that consistency and plausibility. Enough so that the suspension of disbelief can be maintained.

I'm hoping, and thinking, that eventually BW will add on and flesh out this new lore. And then stick with it. Grow the lore. Keep a copy of the lore on their desk for future reference. Work within the parameters of this new lore to grow it; to expand, or deepen the parameters, but in a way that has a clear foundation.

Don't just jump the shark because fuck it.

Personally, with this new installment, I'm willing to let some things sliiide. I know they're trying set up shop and all that. So, okay. However, if there are future games beyond MEA, I would like to see more attention to detail; more depth of lore; and more natural connections between any upcoming new lore - new growth- and prior information.

Exactly. You accept space magic, but whenever it's something you don't like, suddenly space magic is the worst thing in the world. That's why it's hard to take you folks seriously. Also, going to Andromeda is certainly more plausible than bringing Jesus Shepard back, that's a thing dependant of resources, whether you like it or not.

I've bolded the part I want to address. Personally, I've always assumed that these basic elements are exactly the things for which they are looking. As you said, they can't see anything more from so far away.

As to finding worlds teeming with life when they arrive, that's the same thing we see throughout the OT. It's a video game. Of course they're going to have us find a good number of life-bearing worlds. It would be a very dull game, otherwise. ME1 did a better job of exposing us to the barren worlds in the OT.

Still, it is entirely possible and highly likely that they are focusing their marketing exclusively around these life-bearing worlds. Aside from concept art and a few early screen shots, we've mostly seen Elaadan, the desert world, and the other world that may be Habitat 7. I'm sure there are some desolate worlds, too, that would make for dull marketing pieces. (They'd likely have been attacked for having barren, boring worlds in their game, had they used these.)

Doesn't matter how much he throws around "EXPLORATION!", literally everyone can see that using Andromeda as a setting is a way for him to continue milking Mass Effect without having to go back and do something about the shitty endings he wrote.

That's not even remotely true, though. To enable Andromeda as a setting, Mac had to contradict a whole trilogy's worth of technology lore. That's a bigger and more intrusive retcon than simply erasing the endings would have been.
