simpsonsGames publisher Electronic Arts released its latest quarterly financials yesterday, including details on how much money the company made from its smartphone and tablet games.

And how much? EA’s mobile division generated $86m of revenues in the quarter (EA’s fiscal Q3), which was a 23% year-on-year rise. Mobile thus accounted for 9% of the company’s overall sales in the pre-Christmas quarter.

As a quick comparison, EA made $15m from Sony’s PSP and PS Vita combined, and $9m from Nintendo’s various DS handhelds, although Xbox 360 ($277m) and PS3 ($289m) are still the big moneymakers.

In the results, EA said it now has more than 17m mobile users registered for its Origin community. Meanwhile COO Peter Moore said that “mobile game revenues on iOS and Android doubled in size in 2012″ during EA’s analyst call.

He noted that freemium iOS game The Simpsons: Tapped Out reached 3.2m daily active users over the Christmas period, and said that game plus Bejeweled Blitz will be ported to Android in the first quarter of 2013. Moore also confirmed that Real Racing 3 will be released on 28 February, in North America at least.

In response to questions from analysts about whether EA plans to do more in the ‘midcore’ sector of mobile gaming – the area indie game Clash of Clans has been doing so well in – EA Labels president Douglas Gibeau replied in the affirmative.

“Absolutely, we are looking at the midcore segment for mobile,” he said. “Real Racing is a good example of a game that appeals to a core gamer that’s going to be coming out shortly on Android and iOS, and we have a number of titles planned going forward, that will start to reach that audience. We’re big believers in it.”

He added that EA has learned that episodic, themed content for The Simpsons: Tapped out has been a big driver for its growth, particularly its Treehouse of Horrors pack at Halloween. “We have a commitment to ongoing, episodic theme-based content releases for The Simpsons.”

EA’s overall revenues for the quarter were $922m, with ‘digital’ – a category that includes mobile, social games and advertising – accounting for $321m of that.
