I'd figured that everything would be like the Scott Pilgrim series (the graphic novel one, not the motion picture one, because Micheal Cera doesn't exist in the former...or does he? DUN DUN DUNNNNNNN!).
We'd all go about our normal lives until suddenly you are challenged to a fight and the winner gets to keep the remains of the loser (which is represent in some loose change), ninjas are real, deadly, can manuver in sub-space, and might contain sexy phases, vegans and psychics are the same thing, swords can be pulled out of you when you level up, and death is avoidable if you've manged to snag an extra life.
