This IPhone app should be a game in the "Trivial Pursuit" style, with multiple categories and marker(s) for the player(s) which keep track of which categories have been scored in. There should be a game board with special spaces for scoring in each category and a central space for scoring to win the game. A question (text or audio prompt) should be presented to the player when he lands on a space, based on the category of the space, and a mechanism provided for the player or another player to decide whether the answer was correct or not. There should be a die available to determine which space a player lands on. Questions should be in a database to allow for release of additional question sets. Game instructions will be in English but coding should be UTF-8 so that other character sets can be displayed for questions, as this is a language learning game.
A pass-and-play setup is a minimum for multi-player situations, but the ability to play offline and online against others as well would be highly desirable and could be negotiated.
A means of updating the question databases and providing new sets of questions as future subscription content should be provided.
