The value of Mass Effect as a science fiction universe is that it is a critical starting point for discussion about the purpose of humanity in a materialistic universe. Without an answer to that question, there is no real reason for Ender to defeat the Buggers, or for humanity to seek out new life and new civilizations, or for us to not let non-organic life be the torch bearer for intelligence in the universe. Mass Effect confronts us with a female hero of our own creating, with the deepest implications of diversity, with the most dramatic questioning of the value of what it means to be human. Whether you are a feminist, a transhumanist, a theologist, a proponent of space exploration, a pacifist, a human exceptionalist, a bioethicist, a scientist, or a philosopher, Mass Effect demands you rethink your world.
Bold claims, but 1+2 are really good.
