It is, but often you will just get people reiterating the characteristics of their specific God, rather than over-arching characteristics that a thing/being must have in order to even be considered a God. See my short-lived thread: Components of a GodOr do people not think defining "God" is a good first step?
Personally, I agree with the definition given by Copernicus (post 9 of that thread):
"A god is first and foremost an intelligent agent that has absolute control over some aspect of reality."
No other characteristic is as central or necessary to the concept of God.
