According to the dark energy plot, humans were "special". Which ME2 planted the seeds for by speaking of humans genetic diversity. And yes, dark energy was just mentioned by a handful of characters. It was never delved into whatsoever. The few times those words were spoken it always boiled down to "dark energy Idk what it is, but it doesn't make sense". Tali was the only person to even give any insight. Even she wasn't sure what it meant. And that was isolated to the star of that particular system.
How does the Collectors harvesting of humans into a Reaper tie into the organic/synthetic conflict plot that was implemented? Well, the Collectors are Reaper thralls. Shepard threw a wrench in spokes and delayed the invasion back in ME1. The Reapers are simply working through the Collectors to make up for lost time as they travel through dark space. Time they could've spent harvesting. Why are they targeting humans? Idk, seems like Shepard made an impression. He's human. Just my own observation.
Yes Dark Energy itself is pretty much only mentioned by Tali but dark energy and the diversity of humans are equally important to that plot. And the latter is mentioned all over the place, particularly by Mordin. It also ties into the plague in Omega, the Collectors and the Reaper larva.
Without the Dark Energy plot, everything the Collectors do in ME2 is just barely passable as a part in a trilogy. What would've been an "ah-ha" moment when the third game came around and a part that tied the games together pretty much just became an episode of the A-Team or an intermission.
While the detials may not have been final, too me it looks like the plot was decided while ME2 was in development and they switched direction when they changed lead writer.
I think that's the story David wanted to tell or he wouldn't have leaked it.
That's seems like a fair assessment; if there had been a get-out clause that meant Shepard survived at the end, there wouldn't be as many complaints about "plot holes."
I don't think so either, it's a video game and light entertainment, aslong as there was a happy ending to something you spend an evening relaxing with most people would be satisfied.
Personally i never minded if Shepard died, i think sacrificing herself to save the galaxy is an ok ending, but they completely underestimated what Shepard means to the audience.
It's not like a book or a TV show where you merely observe the protaginist, in a video game you embody them. And this particular character has become something of an icon in gaming that fans have grown to love over 5 years.
Makes me abit sad though, needing to constantly cater to an audience is one thing that keeps video games from taking seriously as an artform.
And(if i'm right) changing the story for the final chapter was a serious blunder and i'd rather have a well told and consistent story with a sad ending than a story only made to appeal. Shame i got neither lol
