Spore designed from outset as a franchise

Confirmed for Wii, PS3 and Xbox 360, plus a host of expansion and booster packs for the PC and Mac editions.

Speaking to analysts about Spore, Will Wright and Spore producer Lucy Bradshaw outlined EA's plans to make the ambitious multi-platform title a huge franchise.

Unlike The Sims, Spore has been designed from the outset to accommodate expansion packs, booster packs and microtransactions. Additionally the game will be supported across other media, including a comic book creator using your spore creatures, creature sculptures, additional merchandise and a National Geographic TV show.

In addition to versions for PC, Mac, DS and mobile devices, Spore was also confirmed for Wii, Xbox 360 and PS3 - details of these home console versions were not offered.

Spore has been announced for release worldwide on the weekend of September 7, but EA has also revealed that a creature creation tool is to be released prior to the main game. No release date for the Creature Creation tool has been confirmed.
