Mobile gaming has grown increasingly popular over the last few years. While Nintendo has missed out on a lot of the mobile gaming goodness, Square Enix doesn't want to miss the boat as well. They are launching a Cloud-Powered Final Fantasy XIII in Japan for iOS and Android devices. This will bring more people to spend money on the Square Enix title and also bring better games to Android as the graphics will be rendered server-side and pumped to mobile handsets. While this hasn't worked for competitve shooters on the PC, it could work awesome for mobile games.
The game is delivered as a free, tiny (~20 MB) app, and the entire game is streamed from G-Cluster servers to your device as a video. To accommodate the game’s controls (which were originally built for PlayStation 3 and Xbox 360 controllers), the screen is surrounded by large touch targets that match up with most buttons that would normally be available.
