I adore Mass Effect so much.
With Mass Effect, you make one Shepard, and you stick with them through all three games. You see them struggle. You see their very worst and very best moments. You see them build relationships and end them. You see them make decisions where there are no positive outcomes. You see them sacrifice themselves over and over. You see them tired, and worn out and on the verge of giving up hope. You see them die. But Shepard never gives up. They never stop hoping or fighting.
Throughout the course of all three games, the crew become your friends and your family. You see them grow and change and flourish with (and without) your guidance. You get attached to them. And when some of them become numbers in the ruthless calculus of war, you feel Shepard’s pain. You feel the loss. You mourn them.
And when Shepard finally ends the war, you feel the relief. You feel proud of all of the characters that helped along the way. You feel hope, for the future. And you know the fight was worth it.
