Gamers have been clamoring for Nintendo to jump into the mobile game scene for quite some time, and Nintendo has always been clear that they would not be developing mobile games. Much of the speculation as to reasons why revolved around the fact that Nintendo wouldn't do anything to jeopardize their own portable gaming system, the 3DS, or their brand, which is why Nintendo likely shocked much of the gaming and technology world when they announced a new partnership with mobile gaming publisher DeNA yesterday, stating that together they would be bringing mobile games with some of Nintendo's most memorable characters to smartphones and tablets in the future.
It's still unclear as to what types of games Nintendo and DeNA will produce, but according to reports since the official announcement, Nintendo states they won't be doing ports of games that reside on other systems, meaning gamers won't be able to play Android or iOS official ports of games like Super Mario 3, Super Metroid, Legend of Zelda or any other number of popular Nintendo and Super Nintendo classic titles you find on actual consoles. Rather they'll be making games that are meant for mobile that contain some of the hottest characters Nintendo is known for. They also state that they'll be building games from the ground up designed specifically with the mobile platform in mind and that games will be developed completely in-house according to Nintendo President Satoru Iwata.
This sheds some light on the situation that DeNA will be handling the publishing of games for mobile platforms, but Nintendo will be taking care of all of the development processes. With this being the case, mobile gamers and Nintendo fans can probably rest easy and expect some rather enjoyable mobile titles coming from a well-known icon in the world of gaming. Gamers can also likely expect to see Nintendo's forthcoming mobile titles to hit both Android and iOS, however, Nintendo hasn't specified any particular details in regards to platforms. Both DeNA and Nintendo are slated to have a brand new subscription service that launches towards the end of 2015, so it's possible that some games may end up launching around the same time.
