This was a good quiz when it came out. Now some of the questions are out-dated but you can figure out every answer by trial and error.
The questions were very well picked in my opinion.
The author knew what he did when he set the time required for the timeless glory medal. 20 seconds is probably what an average player would tolerate to bring their fastest time to. At first it would seem challenging but after a while you learn which questions to expect and click on the correct answer almost directly. Each questions always have the alternatives on the same spots, and many question always follow in the same order, so if you get one of them you can learn where to click directly after. The quiz did not award me the medal at first. The pop-up appeared in game. Then I tested to play it in the original Flash and it awarded me it. I waited for long at the finish screen before I got the actual medal so I do not know if it was the Newgrounds Player that was the problem or the time delay.
WAIT FOR SOME TIME WHEN YOU FINISH THE QUIZ FOR THE TIMELESS GLORY MEDAL. IF IT DOES NOT WORK TRY TO PLAY IT IN THE BROWSER WITH THE ORIGINAL FLASH.
