Oh yeah. I mean, before we even got a title, I'd attached myself to this idea of what I kept referring to as Indiana Jones IN SPAAAAAAAAAAAAACE! (yeah, I can't help doing that every time), a plot of staying in the Milky Way and focusing not on major military forces but on a ragtag band of misfit archaeologists digging into the galactic history - focus on the galaxy's past, you don't have to pay too much attention to the present, and these are the kind of people who wouldn't be the major news focus anyway. I knew it wouldn't happen, but I thought it would have been a great way to personalize the narrative better, bring the scale down from a galaxy threatening invasion to a more intimate narrative between the protagonist and antagonist.
And the thing about us being left to speculation for the time being is that, inevitably, due to the sheer number of fans going around, theorizing and coming up with ideas, statistically, there are bound to be plenty of ideas that are better than what will be in the final game. Some of them would bust the budget completely, some of them might be better suited to a sidequest than a full game story plot, some of them are just downright impractical for the medium, but they can easily be better than the finished product, which makes it a letdown because it wasn't THIS.
