The design of both of these sites are preserved on archive.org:
If I recall recorrectly, the uniqueness of their designs was the main reason for keeping these sites around (rather than putting their content on TWOTA). But archive.org preserves the design.
We could add screenshots to the Website Screenshots section and link to these archive.org versions for posterity.
A bit of history: both sites have been abandoned by their creators and full control handed over to me. For a while I have been considering adding the content from these sites to TWOTA and then closing them. The reason for this? In order to make the Panzer Dragoon archive more accessible for visitors, it's easier if all all the content is accessible in a logical place on The Will of the Ancients (especially if we add a search engine to TWOTA in the future). For maintenance/backup purposes it's also simpler just to run one site.
Since I'm in the process of moving the Panzer Dragoon sites anyway, this is a good time to decide. Unless there's a good reason not to, I will probably go ahead with the merger plan.
Edit: I have made this topic public in case other community members wish to provide input.
