Storytelling is your left foot.
Game rules is your right foot.
Playing RPGs is walking.
Some people favor one foot over the other for whatever reason and that's limping, but still walking.
Some people favor only using one foot and just hop, this appears silly for some as it is not really walking.
Some people insist that hopping on one foot is the only way to walk, otherwise you simply aren't walking.
These people are suffering from some form of insanity and should be treated as such.
