Fantastic ending to the best video game series ever.
I have never emotionally connected to a game as much as I have to the Mass Effect series. The first was the best game I have ever played; the second was okay; the third and final installment rivals the first.
As usual, the voice acting (especially for the female Shepard) is top-notch. The story is engaging. The characters have depth and believable plot arcs. And the ending to the saga escapes the worst of videogame cliches.
If you have not played Mass Effect 1 and 2, I highly, highly recommend them before playing the conclusion. Playing through the first two allows you to import your character, and lends weight to the events and relationships in the third.
If you are a gamer and have somehow missed out on this series, you have missed out on the pinnacle of the game designer's craft. Go to it.
