Some hacker-y internet types have taken apart the dictionary included with Scribblenauts and posted the entire, 22,000-words long list to the internets, creating the biggest spoiler in video game history! (At least, in terms of length.)
Among the many nouns I am unfamiliar with are: "ACROSPIRE," "ADRIAMYCIN," and "AEOLIAN HARP," and those are just from the beginning of the "A" section.
If you're going to buy Scribblenauts, I urge you to not look at this list if you're buying Scribblenauts. There's really not point to the game at all if you have a list of words in front of ya!
BTW: Adriamycin is a chemotherapy drug used to treat bladder, breast, head and neck cancer and leukemia, and an Aeolian Harp is a harp played by the wind.
What do you think of the Scribblenauts? Are you planning on buying it? It's out today for the DS, you know.
