Ken's been busy, so some of this may be repetitive.
Force-Sensitive
A character who is not Force-sensitive may choose to become Force-sensitive for 20 Character Points. (There is no training time requirement.)
The character receives one extra Force Point immediately, and must now play under the guidelines for Force-sensitive characters.
I think that and the stuff Trax posted about covers it. The rule book says you must have a teacher to learn Force skills, though the term "Teacher" has a variety of definitions. I'll allow you to take force skills without a teacher, at double cost.
So, no teacher, you can learn a force skill at 1D for 20cp, and it takes 40 days to learn it. Thereafter, the force skill is treated like any other skill, including double costs for not having a teacher.
Now that you're force sensitive, you're subject to some rules (which you were mostly following anyway).
The Responsible Use of Power
A Jedi acts from wisdom, using persuasion and counsel over violence and Force powers. Force powers are to be used to serve the interests of the light. Using the Force for personal aggrandizement, for personal power or wealth, for convenience when other means would be more prudent ? all of these traits are of the dark side.
A Call to Action
A Jedi cannot allow evil to occur by inaction ? a Jedi who voluntarily stands by and allows evil to be committed is encouraging the forces of darkness. Jedi are also bound by the actions of those around them. It is not acceptable for a Jedi to associate with those who wilfully choose to commit evil.
When a Jedi is confronted by a situation where evil is being committed, the Jedi must act to prevent that evil. There are a variety of means at the Jedi's disposal ? persuasion, creating a distraction, armed action or simple mind tricks ? but intervention is necessary.
Failure to follow those rules will earn you dark side points. If you're ever in a position where you will earn a dark side point, I'll warn you and give you a chance to edit your actions. However, if you ever earned your first dark side point, you will never again receive any warnings about dark side points.
Any time you earn a dark side point, I roll a d6. If I roll lower than your total dark side points, your character turns to the dark side and becomes a dark side character.
The Force grows from life, and a Jedi must act to preserve life. Sometimes that means taking lives, but never more than necessary, and a Jedi should consider other options when they can. It's not just about good and evil, it's about preserving life in all it's forms.
I think that covers everything. If you have any questions, let me know.
