Ultimate Otaku Challenge Pic

hitsukuya of deviantart has put forth an interesting challenge. Hidden in this picture is a little more than 50 items that correspond to an anime, manga or game. To prove that you are the Ultimate Otaku, it’s your job to identify 50 items and their corresponding anime/manga/game.

Here's the link to the original picture and here's the link to the answers.

I managed to get around 20 items correct from the top of my head; without the aid of Wiki and the like.

How well can you do?

Best of luck,

Jess
