Of all the criticisms that could fairly be leveled against Scribblenauts, the fact that it only recognizes 22,802 words is not among them. 5TH Cell creative director Jeremiah Slaczka told Fast Company that the leaked word list was not comprehensive, though he said it much more colorfully than we did:
"That was leaked by a hacker who does not know anything," Slaczka said. "It's more than that." Slaczka also revealed the last word to be added to the game's database: "Low Rider." Presumably this was added at the insistence of his friends, all of whom love a low rider.
