Character Background : Spacer
The biggest reason I picked this background was because Shepard would then have a family, something that was missing in the other two backgrounds. And since his family were in navy Shep would already have some advantages in his career (Only wished Hannah Shepard would have accepted the admiral post, and where is his father!?)
Military Background : War Hero
I wanted my Shep to be from the start a hero, a symbol for what the Alliance and humanity stands for. Courage, honor, loyalty. Plus its a nice bonus that he got the "Star of Terra" (The Alliance's Medal of Honor) and renown throughout the Alliance (something I wished was shown more, especially with admirals and Udina)
class : Vanguard/Adept
Once more I wanted my Shep to be a bit special. First I picked Vanguard because it gave me the medium armor and it was a strong balance between a Soldier and an Adept. In ME2 I picked Adept because armor didnt matter anymore and he recieved a heavy weapon later on. It also puts Shepard in a position to help the biotic community that through the years has seen discrimination and abuse.
Gender : Male
Im male so I always play male and play the characther after how I would act. Plus, I like Mark Meers performance.
Morality : Paragon
Since I picked War Hero which transforms Shepard into a symbol I wanted to continue on that path. With my Shep I wanted to show humanity and the rest of the universe of what we are capable of. My years with Star Trek influenced this of course. But my purpose was to evolve our species above greed and self-interest.
The Council : I Saved Them
I saved because of two reasons
1. To keep a unified front in the coming war we need the original council who already knows alot about controlling Citadel space. They have been at this for a long time.
2. The second reason is also the strongest one. When we saved them we showed them that humanity is ready, that we are able to stand firm no matter what the cost. When we are in a crisis in our prime, we never give up, we advance ourself and fight harder than possible.
This decision will also grant humanity a great amount of respect and the Council trust Shepard more than any other Council. In time that may probe fruitfull
Human Representative: I picked Anderson, he knows what needs to be done and doesnt think about the potential political ****storm at all times, he is also more diplomatic than the other option. Plus, I would never pick the **** that is Udina. As the Turians say "Udina is a diplomatic incident waiting to happen".
The Collector Base : Kept It
To give nuclear weapons to cave men can only end in disaster. I felt the same thing about giving something that advanced to humanity that still struggles with greed and imperialism. Especially if it was given to Cerberus, an organisation that will stop at nothing.
Rachni Queen : Shepard is no God and in my book have no right to condemn an entire species to annhilation. Plus, there were evidence that they were indoctrinated and a species cant be condemned because of that, if that is the case then we should condemn every species in the galaxy.
And it seemed like it payed of. The Rachni have kept for themself and will stand ready to aid the galaxy when the times come. Plus, it was also stated that the Rachni are not imperialistic, they just defend themself.
Urdnot Wrex : Saved him, Wrex is a great Krogan and now that he is the leader of the Krogan race it will give us some great support. We can have a functional diplomatic relationship with them and Wrex also want to change the Krogan way of life into something better (by our standard of course)
Virmire : Killed Kaidan. Why? Ash was the LI so it was natural. But in the end Kaidan would have been the better option. He was a naval officer that will be needed in the future. Ash is a common soldier that may not have much to contribute but she is resilient and loyal so that counts for something.
Casulties : Everyone except Kaidan is dead.
Genophage Data : Kept it, it may come to use if we want to give the Krogan a bit higher birthtrate so they dont die out. Plus, scientific data is always great.
Heretics : Spared them. By doing this I hope the geth will see that organics can care about them and that we see them as living beings. A potential ally may be come from this. And we also know that it wasnt the main faction of the Geth that attacked which means they still are neutral.
Samara/Morinth : I chose Samara. Morinth is dangerous and having the loyalty of justicar cant go wrong (as long as you are Paragon

) Anyway, I believe she is more valuable to everyone than Morinth.
Love Interest(s) : Ash at first. I kept to my own species because that felt most right. She has experienced much of the things Shepard has. Military family and all that. But in ME2 after meeting Ash on Horizon I felt the need to break up and pick another one which became Miranda. After getting thru her cold exterior she really was a nice girl, a bit misguided but great.
