Although playing any game on the iPod is a solitary experience-there’s really no effective way to manage multiplayer capabilities, though Spore Origins does have the ability to share creature designs with other players. As you evolve your Spore through the Evolution Mode, you can trade your Spore designs with other Spore Origins players and combat against those designs in an Arena Mode. This requires you to set up an online account on the Spore mobile Web site, and it also requires you to manually import and export your Spore designs (using “DNA codes” that determine how the creature is built). Also, there’s no real interactivity, except for camera control—the Spores fight each other automatically. Still, it can be fun to watch them battle against each other.
