Nokia launches its N-Gage gaming service with a hope to energize an ailing market for mobile gaming.

The new gaming service is one of the cornerstones of Nokia''s new Internet services strategy.

The mobile gaming market suffered an unexpected slump last year due to lack of investment in marketing.

All major cellphone games publishers, including Electronic Arts Inc, Gameloft and Glu Mobile, have signed up for the Nokia platform.

Nokia said last month some 25-30 games titles would be available for N-Gage by mid-2008 and a similar number of titles would be unveiled during the second half of the year.
