Han shot first.

A jedi character is considered a padawan until he hits level 7, or maybe 8. i forget which.

the basic classes are Jedi Guardian (combat focused jedi), Jedi Consular (force focused jedi), Soldier (combat specialist), Scoundrel (rogue character), Tech Specialist (depending on how you build the character, this one can be anything from a medic to an engineer), Force Adept (non jedi force user), and Nobel (a good 'interaction' based class). i think that's all of em in d20.

you can be droids. you can be bounty hunters (i think there's a bounty hunter prestige class, actually), you can be a member of a family of crime lords, etc.

the adventure i've got in mind is set in the old republic era, so 'extended universe', but not 100% accurate to cannon.
