I love Pathfinder (and by extension, have warm fuzzies for 3e than 4e never gave me) but as I work on this adventure (and it could be any dungeon, mystery, sandbox, or railroad) I find the work needed to keep things "balanced" is tiring. Overshoot and you end up with TPKs. Undershoot and its no challenge. Watch your treasure totals so the PCs don't have too much/little wealth for their level. The NPCs which require as much work as a typical PC (and rarely last more than a few rounds anyway).
I have never worried about any of that. I ignore the charts about "appropriate wealth by level" and all that nonsense.
