A new layout has been rolled out on the main page of the site this afternoon. It has new features, including a scrollable quick access list of the Phantasy Star games and two random sections that change on each page access.
The random sections are "Featured," which points out some of the interesting content around the site, and Random Image, which spotlights some of the older images from the site galleries (including fan art!).
If the page looks a bit odd when you first look at it (like a big empty space on the side), reload the page to update your browser's cached copy of the stylesheet. That should give you the full experience.
