There are no classes, you build your character free-form following whatever style you wish. The "classes" you see at character creation only really influence you starting weapons, as everything else can be changed.
The only semblance of an alignment system is reputation. The other set of developed traits are mechanically only there to decide what bonuses you get for being on one side of a scale or the other.
As far as role-playing goes, I guess there's quite a bit of freedom, but I can hardly judge that part of the game, since I have 0 affinity for role-playing.
