As our project will have a narrative/story element within, we decided to look at existing examples of this sort of medium. Targeted Attack: The Game is a narrative experience in the day in the life of a high end app developer and it is the participants job for the app to launch safely without any data breaches.
One method of interactivity the game offers is the ability to use a points based system to answer the situations presented to the user. The user starts with a set number of points which are used to answer questions. If the answer would be a safer choice the more points are spent while weaker answers don’t need as many. This is a “gameification’ method that keeps the user engaged.
Adding the aspect of a game to the experience is something to definitely consider, it can make it more entertaining and keep users engaged with the experience.
