Did you play Mass Effect 2? I hope you did. I find Mass Effect 2 to be a better game, but regardless, the Mass Effect trilogy follows a three step process. Mass Effect 1 lays the groundwork for the universe, Mass Effect 2 builds up the universe and lets you learn about (and fall in love with) everything in that universe as well as warns everything in that universe of an incoming danger. Mass Effect 3 has that danger arrive and kill everything. Every race, planet, character, etc. dies or is affected in a terrible way. Life will never be the same for anyone in that universe again. It was powerful and heartbreaking. It hurt me so much watching all of those characters I fell in love with die, I don’t think I can play 3 again. I go back to 2.
I guess my point is that to appreciate the fall, you need to see the rise. If you haven’t played Mass Effect 2, I strongly recommend it and I think it would make you like 3 even more if you haven’t. Nice list.
