Useless fact of the day: the Sega designers in charge of creating a rival for SuperMario chose Sonic... because they liked the word hedgehog. <3333 Does anyone know where the term "Mary Sue" came from? I don't mean the concept, I know all about that. But why do we call them Mary Sues? Also, could someone please give me or link me to a complete list of the Sandman spin-off comics?
