uhm why are you saying that the jedi order seize to exist?
I think some fans will get angry if you change such a thing in the timeline.
besides, will lucasarts accept that?
and the prestige classes. there is nothing such as a jedi watch men class but perhaps you can take the Force warrior prestige class instead? it should be more fitting to the story.
and the sith marauder class is called "dark side marauder" silly.
nor are there a prestige class called sith assasin.
include sith acolyte instead.
well, i don't know but it seems you are just inventing some prestige classes and using some from the rpg, but wouldn't you get some new true classes?
such as: force adept? that one could be good.
and are you not including other species than simply human? zabrak perhaps or wookie, cereans, kel dors or twi'leks? that would be cool.
/may the force be wiht us.
