Corewars is a simulation game in which competing programs attempt to crash one another through strategic execution techniques.
What's particularly noteworthy about Core Wars is that it comes with a graphical user interface (GTK+) that displays the running programs and statistics for easy monitoring. Additionally, the Redcode language is supported, which is more advanced but also more powerful.
There are two different languages available in Core Wars: Corewars, which is easy to learn, and the aforementioned Redcode. As you progress in the game, you'll need to become more skilled in these languages to create the best program possible.
At the end of the simulation, the "best" program is selected based on a scoring mechanism that takes into account factors such as the number of memory cells it has overwritten, the number of other programs it has crashed, and whether or when it crashed.
Overall, Core Wars is a unique and challenging game that's worth checking out if you're looking for something different. Note that the game requires Glib 1.2.x and Gtk 1.2.x to run. The latest release includes bug fixes and improved Redcode handling.
