The original Neverwinter Nights has experience set to only 10% of what it actually is. For example, if you kill a critter and get 4 points, it would be 40 if experience were 100%. It's one way Bioware controlled advancement in the game, because max level in the OC was, I believe, set at 20.
You can get around that by editing the individual OC modules and setting the mod experience slider to 100% or anything you like up to 200%. Keep in mind that would have no effect on games already in progress. You'd have to start a new game to see the difference.
Quite some time back, I set my OC to 200% (go for the gusto!) and came in with level 21 characters. And yes, the difference was noticeable in several ways. Of course, I didn't bother with the prelude; I just went right into chapter 1.
The only caveat is to avoid having a class level hit 21 or higher; very odd things happen with the experience. Character level (sum of all classes) is not a problem.
I can provide insructions if you want to try this out sometime.
