No catch. The place is amazing. Obviously, they prefer you to pace the downloads, but you're right, it's all there for the taking. I started with them specifically because of the historical stuff; part of my work is in historical recreations for museums and universities, and those egyptian, roman, and biblical costumes were a godsend. The hair on the Egyptian princess is sometimes a little wonky, but everything else is great: the texture on her dress is downright amazing -- I've never seen something that could suggest sparkles as well as that does. Rena and Steve are truly both incredible masters of this stuff.
