One of the games that teachers tested at the Jam Today workshop was Diner Dash, where the player has to manage customer orders in a restaurant within a short period of time, i.e. optimizing sequence of taking orders and providing food. This leads to stressful situations that need to be resolved in a way that customers stay happy.
Green games game, currently being developed, is build upon similar game mechanics.
The feedback to the game play was that it is easy to understand what you have to do, it is fun and addictive and it enables good understanding and learning of hospitality related topics.
Other subject area, that game-based learning with Diner Dash can successfully cover are time management, resilience and project management competences.
