However, I also agree with what @KillerRabbit is saying above about people (including game developers themselves) needing to realize and accept that in the FR setting "good" is the norm and "evil" is an aberration found in villains and monsters that are supposed to be defeated by the good/heroic side. That's the setting, like it or not. And when a game developer very arbitrarily and capriciously tries to change that it will naturally cause hardcore fans of that setting to get pissed off.
I think you may substitute "forgotten realms" for "Faerun", else you would also include all the lower planes. I myself see Faerun as a neutral plane put in a sandwich between good and evil planes.
Now that I think about it, are there any evil centered campains in this setting?
