Watch PAX cosplayers get quizzed on random video game knowledge

It's impossible not to admire all the work that cosplayers put into their costumes (as made evident in our PAX 2013 cosplay gallery). Many spend countless hours perfecting every last stitch in an attempt to accurately portray the characters they've come to love. And while their dedication is incredible, we got to wondering how many would be able to answer super basic video game questions, such as: what was Mario called before he was Mario? Which video game console sold the most units in video game history? And what, exactly, is the maximum achievable score one can attain via a perfect performance in the original Pac-Man arcade? These are their answers (and super awesome costumes).
