September 12th: A Toy World is a politically charged serious game that tackles themes surrounding the USA's War on Terror. Set in a Middle Eastern marketplace, the game is presented from a top-down isometric perspective, allowing players to observe the interactions between civilians and terrorists within the environment. The primary mechanics involve scrolling the camera and launching missiles at targets, with a delay before impact. The game emphasizes the consequences of violence, as killing terrorists leads to civilians becoming radicalized, creating a cycle of conflict.

The game features destructible environments, where buildings can be destroyed by missile strikes, resulting in civilian casualties from the blast radius. Over time, the game simulates a form of regeneration, with buildings gradually reconstructed and some terrorists reverting to civilian status. However, the haunting reality remains that a portion of the population will always remain radicalized. This unique gameplay approach invites players to reflect on the complex moral implications of warfare and its effects on society.
