JMich: In a proper level scaling system, there are no level 1-5 areas. All areas are at least your level, so the path I mentioned above wouldn't be "10-15"->"7-8"->"4-6"->"1-3"->"15-17" but it would be "15"->"15".
jamotide: Well it is in the original campaign, because the enemies scale to your level within that range. And since you listed the xp possibilities we can see that you will always encounter enemies your level in the beginning of a new area. But since scaling sucks, they removed that in the much improved addons and part 2.
You are mixing stuff up. The path I'm saying above has nothing to do with Neverwinter Nights, it was a reply to Crossmando about how Fallout's map is, and what a game has to avoid. Having me backtrack through lower level areas, while the enemies still fight me is something to be avoided.
As for NWN, you still haven't read
post 233. While the first 2 chapters are semi-ok (you start Chapter 1 as level 1, with the enemies being levels 1-5, you start Chapter 2 as level 6.5 with the enemies being 5-10), from the beginning of Chapter 3 you start being overpowered (you start Chapter 3 as level 13 with enemies being 10-15, so the equivalent of having already finished one of the 3 areas). By the time you reach Chapter 4, you are level 17, with the enemies being 15-17, and 17 are the end area enemies, that by the time you reach them you are already level 19 or 20. And for Chapter 5, you begin it as powerful as you should be at the end.
So no, the enemies don't scale to your level. And yes, I am repeating my self.
jamotide: No, it is just designing enemies in a linear game. It has nothing to do with area scaling. If its too easy later, they should have just put stronger enemies in there.
It's too easy if you do all 3 areas. If you only do the 2 areas that are needed to continue, you begin each chapter at a much lower level, so if you do use stronger enemies, you won't be able to proceed.
If you only do the minimum, you begin Chapter 2 as level 5, Chapter 3 as level 10, Chapter 4 as level 15 and Chapter 5 as level 17. If the enemies are placed for a level 6.5, 13, 17 and 20 respectively, you will be severely underleveled, so you will have a much harder time, if you even manage to make it. Would you then scale the enemies down if the player is underleveled?
P.S. How exactly does the enemy level scale with areas? Because so far when I say area scaling I mean that specific areas have enemies of a set level, and said level won't go up or down. That is why I use area scaling, area based and hand placed for the same thing, because they are the same thing.
