I'm not sure what you mean. Dark energy never went away. But I felt that in the beginning, a lot of the technology and science in ME were at least based off of real-world science, even if they weren't actually realistic, and that the setting kind of got away from that as it went on. I'd like to see the next game reverse that, and I think that should be easier to do now that there's implicitly a smaller-scale plot than Invasion of Space Cthulhu.

Or do you mean the dark energy plotline? I never liked it as the proposed grand plot to the series, but I do think we need an explanation for what was up with Dholen.
