Xconq is a general strategy game system. It is a complete system that includes all the components: a portable engine, graphical interfaces for several platforms, multiple AIs, networking for multi-player games, and an extensive game library. The games in the library range from ancient civilizations to the far future, from simple to very complicated. Xconq's forte is turn-based strategy with overhead map views, using a hexagonally-tiled world. It includes a game design language GDL, which is a declarative language that lets you define the units, terrain, etc, then fill in tables defining their interaction. Literally hundreds of different properties and tables are available to the game designer.
