I'm making mine for me. so I'm doing all the Noble 6 stuff first, then I'll start with all the rest of the stuff I want. If that make sense to you. I have never play the game so I really wouldn't feel that I need to be true to a character. If you look I used MY call sign on the armor (THORN). Of course I did have to laugh when I found out that the in game person was called Thorm.
Just remember you're building a Spartan, They change/upgrade every chance they can.
