"Spore" is coming to more than the PC and Mac in September, but the experience is - a little - limited. EA wants to fix that.
One of the big draws of "Spore" is the potentially unlimited supply of user-generated content from the Sporepedia. You can't do that on the iPhone, mobile or DS versions of "Spore." Not yet, anyway.
While checking out the minimalist iPhone version at E3 (it's only the amoeba stage), MTV frowned at the lack of interoperability with the rest of the "Spore" universe. A nearby Electronic Arts representative told them the developers are looking into the issue.
