That's true, with a bit of acceptable fudging they could get the universe up and running in a decade or so. I admit I'm a little biased in that I think Control is the universe that would be the most interesting to explore. Destroy has this post-apocalyptic feel to it that I don't like.

Whichever way Bioware goes, they're going to have to make some decisions canon. There's too much variance in the universe-changing choices for the Geth, Quarians, Krogan and the ending state of Earth.
