About the Jomini Engine

The JominiEngine is an emerging, distributed, scalable game engine for historical massive multiplayer online role-playing games (MMORPGs). Core game and system design principles of this engine are historical accuracy of the game model and scalability of the system to large numbers of players. The intended application domain is education in history, to provide an "interactive history“ experience. Specifically, the engine has been instantiated to a concrete game, Overlord: Age of Magna Carta, a game set on mainland Britain in the time period of 1194-1225.

The implementation of the game engine focuses on modularity, extensibility and scalability, so that it can be instantiated for different time periods, and extended to also cover different application domains. We therefore view this game engine as a "motherboard“ for developing educational tools with varying topic areas and learning objectives. Technically outstanding features of the implementation are the use of Riak as a non-SQL database and of C# as a programming language.

This research is supported by the SICSA Challenge grant (networking grant): JominiEngine: A Serious Game Engine Across Learning Domains.
