Digital Chocolate's Army Attack! found a highly viable niche in strategic war gamers on Facebook, peaking near 600K of daily active users during 2011 and continues its success on other platforms. The lecture will walk the audience through development and post-launch learnings from the game. Creative director Aki Järvinen will present what went right and what went wrong with the project and summarize the findings into the key contexts of social game development: virtual goods, metrics and software as service.
