By giving the user complete control over what objects who can use in the world, rather than limiting whom to a small set of objects as in most games, 5TH Cell has created a new concept for gaming called Emergent Gaming. Essentially, a gamer will find a solution to a certain puzzle that even the game developers never thought of, rather than just one solution for one puzzle.
The best example can be found on the very first level. There are multiple ways to approach the puzzle; one could either destroy the tree, knock the Starite out of the tree, or get Maxwell up the tree. From these three possibilities an infinite number of objects can be used. Every single item that can be thrown, from Footballs to Shurikens, can be used to loosen the Starite. Meanwhile, anything from fire, to an Axe, to Termites can be used to destroy the tree. And still, Maxwell can fly, climb, or bounce his way to the tree. However, even these basic examples only scratch the surface, assuming Maxwell will just use one item to get the Starite. He could just as easily use a Triangle, Plank, and Weight to catapult himself into the tree.
The concept is simple enough: give the gamer every tool rather than only a few tools, and see what combinations who can come up with. While this approach makes level design difficult to ensure that gamers will not find cheap solutions to certain puzzles, the freedom given is worth the effort. It is only through the sheer number of nouns available in Scribblenauts that this unique idea of Emergent Gaming is even possible, and it could lead to some extremely interesting games in the near future.
