Shocked that I get to be first to mention Green Ronin's Mythic Vistas: The Trojan War (Trojan War | Geek Native).
*coff*
Green Ronin's Mythic Vistas series has a book on the Trojan War.

I can also recommend Mythic Vistas: Trojan War and Relics & Rituals: Olympus. R&R Olympus didn't QUITE blow me away to the level that Relics & Rituals: Excalibur did, but it's still pretty good. Except the art (they use Leif Jones a lot, whose style I find repellent.)
