Everything about Mass Effect is grand: The setting, the story, and the characters. Everything is set in such a massive environment, filled with choices that effect how the game progresses. Everyone’s experience is different in some way. In Mass Effect 3 The monsterous Reapers have invaded Earth. The home ground is now under attack and our very cities are getting destroyed. It’s up to you/Commander Shepard to save the galaxy. No big deal, how hard can that be?
