ICBM3D (Inter-Continental Ballistic Missiles, 3D) is a 3D game of defense. Like the original "Missile Command" and its clones, this game places you in control of Anti-ICBM weapons which you use to destroy an onslaught of missiles (and other nasties) which are dropping onto your nation. The game ends when your cities have all been destroyed. You only gain replacement cities by acheiving certain score thresholds during each attack. The differences between Missile Command and ICBM3D is that ICBM3D, as the name suggests, provides a 3D perspective. You take advantage of X-Window's 3-button mouse to control your firing sight in 3-dimensions and change your viewpoint.

Neohunt is an enhanced variant of hunt, a multiplayer game in which you run around a maze and shoot your friends before they shoot you. It is also an artifact of an earlier age, to be used either as nostalgia (if you remember the eighties) or as an example of how much better things are today (if you don't).

GCompris is an educational software suite with numerous activities for children aged 2 to 10. Some of the activities are game-orientated, but nonetheless still educational. These include computer discovery (keyboard, mouse, different mouse gestures), algebra (table memory, enumeration, double entry table, mirror image), science (the canal lock, the water cycle, the submarine, electric simulation), geography (place the country on the map), games (chess, memory, connect 4, oware, sudoku), reading practice, and others (learn to tell time, puzzles of famous paintings, vector drawing, cartoon making, etc.). It currently offers in excess of 100 activities, and more are being developed.
yuxtapa is a multiplayer real-time CLI game. It looks like a roguelike, but feels like a multiplayer 1st-person shooter with a focus on team play. The idea is to take the "feel" of such team based multiplayer games as Enemy Territory into an NCurses-based game with roguelike controls. Like roguelikes, yuxtapa is lightweight but surprisingly rich under the crude surface. It features several classes from which to choose, each with a different special ability, randomly generated maps which can also be saved and reloaded, and multiple game modes or objectives.
