Hoping to establish itself in the online space, EA took the lid off of Nucleus, a new cross-platform “identity system” that will store your profile such as likes, dislikes, friends and achievements, among other things.

The system will carry a gamer’s identity everywhere they go – across games and platforms – so that the reputation a gamer establishes follows him everywhere.

In addition, EA Online has built a set of powerful backend tools that will make micro-transactions a bigger part of the gaming experience. The identity system will play a major role in this, being integrated into titles like Spore and upcoming titles from EA Sports.
