Supplements for a Rifts-Inspired D20 Campaign

I've run a Rifts-inspired D20 campaign before, and it was a resounding success despite being relatively short-lived. These are the books that I recommend using if you plan to go ahead with such a setting:

• Any fantasy themed 3.5 or Pathfinder materials that seem appropriate
• D20 Modern
• D20 Future
• D20 Future Tech
• D20 Apocalypse
• Urban Arcana

I've already mentioned that these books are likely to be great additions to the idea, but I haven't actually read them yet.

• Broken Earth
• Pathfinder Campaign Setting: Technology Guide

Any recommendations for other products that would fit?
