Mustrum_Ridcully said:How important is this? In 3rd edition, I think it would be pretty important. If you hand out extra GP for completing a task, this might give the characters more equipment than they should have by their level. If you hand out XP, they might have too little. If you assign a CR to a story award, you can determine appropriate treasuer and XP fitting the system. Still doesn't give you a guideline how much something is worth, and how you should handle such rewards if they only apply to specific characters.
That's a good point: one of 3E's problems that it is too easily upset by an overage in XP or gold than previous editions. In 1E or 2E an accidental "Monty" haul was more easily resolved because, generally speaking, what the PCs bought with that exra 50K gp didn't have that big of an impact on play. In 3E, not so much. And a lot more XP was required to level, so a too-big XP reward wouldn't have a great impact over the length of a few sessions.
However, one benefit of not having a structured system for doling out "non combat" XP is that the DM can determine the relative value of the non-combat stuff to the players, and thereby define its relative importance in the campaign. If the non-combat stuff nets you twice the XP, for example, it indicates that the DM thinks it is twice as important (without being forced to put twice as many encounters of this type in the adventure).
