Game Balance in Your Group
There are a number of issues that can affect overall game balance, and specifically the relative "worth" of encounters, which are not directly based on the level of the creatures involved. Since many of these variables are part of having a flexible system that allows for extensive freedom for players and GMs, we prefer to simply accept them and warn you in advance.
Please note that the variables below do not have a "right" value. Many people honestly differ in their preferences in these issues, and we are not taking a side. Instead, we are offering ways to calibrate your encounters and campaign design to a set of preferences or tendencies that may exist in your gaming group.
