Essentially it does not represent medieval Europe because it draws upon hundreds of years of history (incl. the Early Modern period, into the nineteenth-century according to one Ph.D. columnist) and events which did not occur concurrently. Medieval phenomena and trivia are meshed into a fictional world with fantastical elements. The societies do not act as medieval societies would, much of the politics would be utterly alien to medieval societies, and the climate and seasons mean major parts of medieval society are cut out (ie. the feast days which formed the calendar of medieval activity).

It's medievalism, a different type of medievalism to nineteenth- or most twentieth-century ones, but medievalism all the same.
