Interesting. Not sure it would have answered all of the questions people have about the ending, but most, certainly. Regardless of how one feels about the ending (and speaking as someone who tolerates it) - accepting the deus-ex-machina, accepting the three choices as being the only ones open to Shepard, not refuting the Star Childs assertions about the inevitability of destruction
1- Joker-escaping-in-the-Normandy seems literally impossible. They
must have been planning a clip showing him picking up the squadmates, right? It would've been so easy...
I think the relationships between Shepard and Anderson and Shepard and Hackett (and, where applicable, Shepard and Hannah Shepard) are some of the most interesting. To the squadmates, s/he is Shepard-Commander (although subtly different in each case; Garrus' relationship in particular is that of an equal), someone to be admired and respected, but also looked up to for inspiration. Anderson and Hackett draw out a different side of the character; they show their influence on Shepard.
Also, internet. "Decimated." You keep using that word. It does not mean what you think it means. (Christ, having the fleets only being decimated would be a great victory. Or am I being too picky here?

)
Also, you know what would've been cool? Elcor-mounted Thanix missiles.
1Y'know, maybe Bioware are trying to be too clever with this...
Shepard: Why?
Sovereign: I am beyond your comprehension.
Shepard: But why?
Harbinger: You do not yet comprehend your place in things.
Shepard: Whywhywhytellmewhy?
StarChild: yo dawg, i heard you don't want synthetics to kill organics so i made synthetics to kill organics so organics can't make synthetics to kill organics
Shepard: That makes no sense.
Sovereign and Harbinger: Told you so...
