What determines how well the battle for Earth goes? Your War Assets. What determines how well the Crucible's activation goes, as well as what options you have available for the Crucible? Your War Assets.

What determines your War Assets? Your choices.

I also have no idea how the Crucible apparently makes all of your previous choices pointless. Somehow I doubt that it gained the power to revive all of the races and characters that die as a result of your actions when I wasn't looking.
