Those of us who have completed ME3 by now know that the reason for the Reaper's existence is to clense the galaxy for all life, or else synthetics would eventually kill all organics. Finally, they would harvest all life and turn them into reapers, so that they don't disappear forever. I think we all can agree this is pretty stupid. So to ensure machines doesn't kill organics, a bunch of machines kill everyone instead. Fool proof idea. Not to mention the fact that I just made the Quarian and Geth BFF's.
Anyways, rumors are surfacing suggesting that ME3 was supposed to be all about dark energy. As you might know, most of the universe is based on dark matter. In the Mass Effect universe, biotics and space travel manipulate the dark energy to function. This is causing all kinds of bad things, and will eventually cause the universe to impolde. Well, the Reapers know this, and they've established the Mass Relays and the Cycle to cleanse the universe every 50.000, so that people won't ruin it forever. Remember that sun on Haestrom that was going super nova during Tali's recruitment mission in ME2? Yup, that would happen everywhere if not for the reapers.
I like this idea much better, as it would suggest that the reapers are both good and bad. They're intention is certainly good, but they're going about it all the wrong ways. And though it might not be the most original plot twist or the best one, it would certainly be a lot better than the reason that made it into the final game.
So what do you guys think? Would you prefer it the way it is, or would it be better with the dark energy plot?
