Is there anything worth downloading off it?

[The Rose Dragon]

Freely, or after you pay for it?

The former includes Witchcraft (http://www.rpgnow.com/product_info.php?products_id=692&it=1), and that's pretty much it. The latter includes things like Exalted, All Flesh Must Be Eaten, Ghosts of Albion, Qin: the Warring States, Mutants & Masterminds, Faery's Tale Deluxe, Weapons of the Gods and Spirit of the Century.

Frost and Fur, From Stone to Steel, Book of Templates Deluxe Edition 3.5, Green Ronin's Advanced Bestiary, True20, the Mythic Vistas series, various d20 Modern titles too if you're into that, BRP, Shadowrun titles, Castles and Crusades...

Yeah, I'd say there is.
