Countering gods' wishes

[Halaster Blackcloak]

Yeah, I'm on a posting rampage today. Looks like both Garkal and myself decided to start some new threads at the same time.

So, in the 1E DMG, on pg. 130, it says:

"Note that no wish is able to cancel the decrees of god-like beings, unless it comes from another such creature."

I've always played it that way but I'm not sure I ever noticed this particular sentence before. I do like that it is a written rule.
