When I played the Heroes game tonight I noticed a question with the statement "whose flag is shown here". So I went and checked the quiz afterward, and indeed it was a photo quiz. (A well-written one, of course.)
My understanding was, however, that photo quizzes and brain teasers were not to be a part of the question pool? Has that changed? Or was that just an oversight?
