Anime figures? You totally beat me, dude. But hey! Maybe not.
My nerd level is not measured by toys, it's measured by books.
Behold my humble trilingual science fiction and fantasy collection.
Asimov's Foundation Trilogy and Galactic Empire Trilogy. "Magical world of fantasy: Wizards" edited by Asimov. Space Opera.
Lord of the Rings hardcover Trilogy. Anne McCaffrey's Dragonriders Trilogy (Interesting fact: the publisher marked the first book as fantasy, but all the rest are Sci-fi.) Phillip Dick's The man in the high castle (alternative history) Roger MacBride Allen's Utopia, set in Asimov's universe.
Some Russian science fiction and fantasy books. Frank Herbert's Dune. And of course, no sci-fi collection is complete without The Hitchhiker's guide to the galaxy.
