Electronic Arts have revealed a new game service at E3 this week - called Nucleus - the service will help players track preferences, scores and friends.

You can challenge contacts to bouts and it'll cleverly work on all formats.

Spore and Heroes will be covered initially, as will all Sports' titles.

25 games will be part of Nucleus by 2009 and micro-transactions will be a part of the deal, too.

Napster creator Shawn Fanning is behind Nucleus, and he explained the new offering during EA's E3 press briefing.

All formats. Impressive. More on this soon.
