I have some disdain for the intro that it seems weapon heavy, with the emphasis on the gun and the hard light sword. Is that just me? Mass Effect's gameplay is largely built around combat, but no one's buying Mass Effect for the gameplay; they buy it for the story and universe.
If they bottle up a couple of guys and put them on an experimental mission to Andromeda before all of the Reaper shit goes down, that seems to undercut the universe angle a bit while sidestepping the story issue.
I mean that in a good way. How do you resolve an ending that players themselves decided individually. Not doing it seems the wisest option until you're wise enough to find a way to do it.
