Memes were actually a great way to sell the original Scribblenauts. When they released it at E3, the Longcat and keyboard cat memes were relatively new. There were a few Scribblenauts demoes out. When people discovered that memes, especially NEW memes, were in the game, it helped gained popularity and made Scribblenauts a sleeper hit.
