Mass Effect 3 in my opinion is an improvement over the first two parts. Although you follow a storyline you hardly feel to be pushed to a path. many decisions you meet have far-reaching consequences on the rest of the game. When importing a character from the previous version, you can clearly see the impact of its decisions at that time. .Each Experienced in this way their own version of history. Due to this concept, I would advise everyone to play the predecessor before the 3rd part. While you can read the story at any time in the encyclopedia, but to experience it 'live' and shape is much more exciting.
Like the previous parts of Mass Effect 3 is a very nice mix of RPG and Action in sci-fi style. Where just in the last part, the action seems somewhat superficial, when it was still part in 2 or 1. But not to the extent that it bothered me.
In addition to the single player, there is also a multiplayer component, which I have not been tested and therefore can not comment.
For me this is definitely a recommendation for everyone who is interested in the genre.
