How does spore differ from spore creature creator

Spore Creature Creator is where you can only create creatures and share them online. In Spore, you can bring those creatures to life and into your game. You may meet your different creatures throughout the entire Spore game, by either you, or your friends. You can also choose what content you want to be in your game, either specifically all of your creation or a buddy's. Or if you are looking for something more accurate, you can make a Sporecast of creations and select it.
