Nintendo of America have issued a press release detailing improvements to the Wii's online service:

"No one wants to play the same game forever. However, sometimes it is impractical, both for Nintendo and for our customers, to release a new sequel to all our games every year. In order to solve this problem, Nintendo will begin offering the Wii Want MoreTM service this May. By logging into the Wii Shop Channel players will be able to purchase new content for games they already own for a fraction of the price it would cost to buy a new game.

We are pleased to announce that one of 27 games to make use of the Wii Want More service at its launch will be none other than our very own best selling Super Smash Bros.® Brawl! Starting May 13, 2008, players will be able to add four undisclosed new characters and two new stages to the already large roster included in the stand-alone game for only 10.00 USD. Our customers will be even more pleased to discover that this particular package will be offered completely free of charge for the first month after the launch of Wii Want More. A better deal has never been offered by any company in the Video Game industry.

In addition to Super Smash Bros. Brawl, Nintendo will offer content for The Legend of Zelda®: Twilight Princess, Fire EmblemTM: Radiant Dawn, Metroid® Prime 3: Corruption, and Mario Kart® Wii, as well as several titles available through the Wii WareTM service. Wii Want More will also allow our numerous third party developers to offer downloadable content for both previously released and upcoming games. This spring, be ready to ask for more!

Remember that Wii features parental controls that let adults manage the content their children can access. For more information about this and other Wii features, visit Wii.com."
