the overarching rule of efficacious blandishment
Most RPG’s have the equivalent of what the Dying Earth calls ‘the overarching rule of efficacious blandishment,’ a rule which says, ‘you’re the referee, apply (or ignore) the rules as you see fit.’ Therefore I have no hesitation in voting yes.
Also
When running any game I decide whether the players:
1) succeed without the need to make a roll,
2) need to make a roll to see whether or not they succeed, or
3) don’t need to make a roll because they can’t succeed.
There are no other options, so that, in essence, is a RPG.
