I am a huge Mass Effect fan, and I know the ins and outs of the series like the back of my hand. I believe this series is the culmination everything great of nearly 70 years of Sci-Fi: from the bowels of Forbidden Planet, up to the latest Star Trek.
While in my opinion the first Mass Effect is the best, the 2nd and 3rd entries are incredibly solid. I believe 98% of Mass Effect 3 was the best game I've ever played. While I disliked the ending, the Extended Cut made me like and appreciate it more. Still, planet exploration (a la the Mako) was missed, and there was not enough RPG mechanics.
Also, I like to look into the developers minds into the creation of some aspects of the game. Most notably I focus on the names of planets, systems, vehicles, people, etc. Most often you will see me editing or adding the Trivia sections of some pages where I feel it is worth noting what something is named after, and the reasoning behind it.
Anyways, if you have a concern about a page that I edited, or a question, feel free to leave it on my talk page and I'll try to respond promptly.
