Good quiz! I was convinced Niue has played in it once, but think that was the emerging nations.. along with Malta. Technically, as it doesn't state it's the mens comp, then Canada and Brazil could be on here for the Womens comp (and Spain for Wheelchair if I'm being a total pedant)
Glad you enjoyed the quiz, changed the description to specify men's (cheers for the heads up). I'll make separate quizzes for Wheelchair and Women's World Cup.
