I am working on my version of Halo type Spartans for a game I am going to run.
Spartans were designed to be inherently Loyal and Obedient ( Yes the Master Chief was an Atypical example, but then He was also beyond the original Program, almost a Sole survivor so some what outside most Command structures.)
But would you represent this in a Stat penalty to Presence?
I think they had a decent SD bonus for self control over ones self but,
Presence is represent as control of ones own mind, courage, bearing and self esteem.
seems that also should be high.... yet there is that overriding, designed in loyalty to the Human race and the command structure.
Perhaps it should just be a "Racial" Flaw? ( racial term being used loosely here as though they are human they are genetically enhanced.
