I just compiled an excel file that has all the updates and videos that you can watch anytime, also includes items and of course all the updates in order and catagorized from oldest to newest.
Warning this file is somewhat big 19mb, because it includes all the videos.
info: To scroll through the categories click on the bottom subpages while excel is opened.
Also have a decent update of mediaplayer or winamp becuase you need to play the videos.
And finally try clicking on the character picture for information and anything colored blue is clickable.
