Well, I didn't realize this until recently, but AGD Interactive ("Anonymous Game Developers") did a massive overhaul of King's Quest 2 back in 2003. Not only did they improve the graphics by several orders of magnitude (check out this page, and click on "KQ2VGA Feature Page" to see the awesome header on this page that shows the difference) and add mouse control, but they added full music and several acres of content and new characters and puzzles that the original game never had. It's as if Sierra made an entirely new game in the style of 5 and 6, my favorite two of the series.
I am INCREDIBLY STOKED about this, you guys. You have no idea. This is like a Christmas present for the part of me that is 12.
I can't wait to tame the pegasus, but I have to find Neptune's trident first.
