Hi
Is there some kind of a mod that doesn't put the level limit to 20?
I always reach 20, and then after that experience doesn't matter anymore, there is no more progress in skills etc.
I think I could use 2-3 more levels
Kotor2 is great, it gives more levels than you can reach, so most players (unless they cheat) level up all the way to the end of the game, with no stopping.
20 levels
As far as I know, I don't think there is a mod to modify the level cap. Sorry, but you will have to live with it.
