Mass Effect 3 - It's all about the journey
I started playing the series Mass Effect from the very beginning. It was a solid game with rough edges but certainly a step in the right direction when it comes to story driven action rpg's. Characters introduced were amazing in depth, personality and strong in either what I found to be my capacity to either love them or hate them. Mass Effect 2 followed it all up being a true masterpiece of a sequel playing the difficult role of other great trilogies, notably "Empire Strikes Back" and "Halo 2"
I rarely come across games where you are forced to make moral judgement and then face the consequences in spades. Mass Effect 3 brings this into fruition as it's predecessors but does it at a galactic scale. There are key moments in this game where I had to pause and really sit back and "think". My moral core was put to the test so to say. Having invested so much in each character, seeing them make the huge sacrifices necessary to get to this point, then seeing them die was heart wrenching.
This is probably not a game for those just starting out. Personally I would recommend you at least play Mass Effect 2 before playing Mass Effect 3. Given the scale of the story it's better to have full context of what's happening.
Given this is the last of the games in the series, I can honestly say these are a set of games to remember. The world created for this game rivals that of many other epic Sci-Fi universes, "Star Wars", "Star Trek", "Babylon 5" and "Firefly". While I am sad it is now at an end, I hope Bioware decides to move on to another game in the same world.
