Massive is starting to seem like too small a word for the scale of this trilogy.
It’s amazing what difference two years can make in a franchise. Mass Effect has gone from a great game to an unforgettable one. However, this is mostly due to how incredibly well it built upon the decisions you made in the first game. Mass Effect 2′s enjoyment is more dependent on playing its prequel than any game I have ever played. I strongly stress that most of the value from this game comes from playing this after playing Mass Effect with an imported character. The impact of the game’s plot, characters, choices, and universe will be significantly less if you haven’t played the original. If you haven’t you’ll enjoy the outstanding gameplay, but if you have, prepare for an experience of unmatched scale.
