From Wikipedia: The Elder Scrolls Travels: Oblivion is an Elder Scrolls Travels game available on Java-enabled cell phones. It follows the storyline established in the console and PC versions of Oblivion, but a player does not require any previous experience with these versions to enjoy the game. Oblivion Mobile includes ten main levels and four optional quests. Eight classes are available to choose from, and each has access to different armor, weapons, and spells, as well as a number of items available to them all.
