Sean, I like rule 6.  Got to get our group to institute that one.
I don't however, like gms who declare that their word is law.  They tend to be inflexible, piss off the players, and end up not being invited back.  We had one guy like that, who tried to force the players into his carefully crafted plotline, like Lodge in Gamers 2.  Unlike Lodge, however, he didn't change, and he is no longer welcomed at our table.  Our group sometimes takes side paths, or goes in a direction the GM didn't expect.  A good GM will find a way to work with that to get the party to their goal without forcing them or using the old 'the all-powerful wizard teleports you to the ruins, tells you what to do, and then teleports you back' manouvre.
