How deep do you normally go in your role playing? Reason I ask is that I tried this once before without any real thought into the character and it just ended up as an Orc wearing Blades armor. Not too Samurai-ish if you ask me. Then, I started new and created Balgrol Gro Musashi and it became a much more enjoyable play through.
Gear: Blades Armor
Weapon: Duel wield just like the greatest samurai of them all - Mushashi.
Major Skills: Heavy Armor, One Hand, Block
Minor skills: Smithing, Alchemy, Enchanting (played as meditating and infusing weapons with souls of the ancients), Archery
I had the option of going one of two ways with Balgrol gro Mushasi: 1) Good, in retained service to a good lord/god (i.e., Paladin type) upholding honor, rightness, honor, etc. as in traditional code of Bushido.; or 2) Evil, in retained service to a Daedric Lord to do his/her bidding.
Wont tell you which one I chose, you can do this yourself and pick which route to take.
This is just kind of a skim off the top of the build I did.
