Angband is a single-player, text-based, dungeon simulation derived from the game Moria, which was in turn based on Rogue. It is often described as a "roguelike" game because the look and feel of the game is still quite similar to Rogue (though there are now graphical tiles available if you dislike ASCII gaming). Angband has been in more or less continuous development since the early 1990s.

The ultimate goal of the game is to develop a character strong enough to defeat Morgoth, who resides on dungeon level 100. Upon doing so, you will receive the exalted status of "winner" and your character may retire. To achieve this you will need to explore numerous dungeon levels, defeat many foes and sift through a great deal of treasure.

Angband is a reference to Morgoth's "prison of iron" in the world of Middle-Earth, created by J.R.R. Tolkien.

The rules are simple: you ride a light cycle (a kind of motorbike that can only turn 90 degrees at a time, leaves a wall behind and cannot be stopped) and have to avoid running into walls while at the same time you have to try to get your opponent to run into them.

BZFlag is a 3D multi-player multiplatform tank battle game that allows users to play against each other in a network environment. There are five teams: red, green, blue, purple and rogue (rogue tanks are black). Destroying a player on another team scores a win, while being destroyed or destroying a teammate scores a loss. Rogues have no teammates (not even other rogues), so they cannot shoot teammates and they do not have a team score.

There are two main styles of play: capture-the-flag and free-for-all. In capture-the-flag, each team (except rogues) has a team base and each team with at least one player has a team flag. The object is to capture an enemy team's flag by bringing it to your team's base. This destroys every player on the captured team, subtracts one from that team's score, and adds one to your team's score. In free-for-all, there are no team flags or team bases. The object is simply to get as high a score as possible.

This package installs the BZFlag client compatible with 2.4.x BZFlag servers.

CGoban (Complete Goban) is a computerized board on which you can play the game of Go against another player, view and edit smart-go files, and connect to Go servers on the internet. It can also interface with computer Go programs such as GNU Go that speak the Go modem protocol.

Go is an ancient game originated from China, with a definite history of over 3000 years, although there are historians who say that the game was invented more than 4000 years ago. The Chinese call the game Weiqi, other names for Go include Baduk (Korean), Igo (Japanese), and Goe (Taiwanese).

In this game, each player tries to exert more influence on territory than her opponent, using threats of death, capture, or isolation. It is, therefore, a symbolic representation of the relationships between nations. Go is getting increasingly popular around the world, especially in Asian, European and American countries, with many worldwide competitions being held.

The game of Go is played on a board. The Go set is comprised of the board, together with 181 black and 180 white stones. The standard board has 19 lines by 19 lines, but 13x13 and 9x9 boards can also be used. However, the 9x9 and 13x13 boards are usually for beginners; more advanced players would prefer the traditional 19x19 board.

Compared to International Chess and Chinese Chess, Go has far fewer rules. Yet this allowed for all sorts of moves to be played, so Go can be a more intellectually challenging game than the other two types of Chess. Nonetheless, Go is not a difficult game to learn, so have a fun time playing the game with your friends.

Each player controls a team of several hedgehogs. During the course of the game, players take turns with one of their hedgehogs. They then use whatever tools and weapons are available to attack and kill the opponents' hedgehogs, thereby winning the game. Hedgehogs may move around the terrain in a variety of ways, normally by walking and jumping but also by using particular tools such as the "Rope" or "Parachute", to move to otherwise inaccessible areas. Each turn is time-limited to ensure that players do not hold up the game with excessive thinking or moving.

A large variety of tools and weapons are available for players during the game: Grenade, Cluster Bomb, Bazooka, UFO, Homing Bee, Shotgun, Desert Eagle, Fire Punch, Baseball Bat, Dynamite, Mine, Rope, Pneumatic pick, Parachute. Most weapons, when used, cause explosions that deform the terrain, removing circular chunks. The landscape is an island floating on a body of water, or a restricted cave with water at the bottom. A hedgehog dies when it enters the water (either by falling off the island, or through a hole in the bottom of it), it is thrown off either side of the arena or when its health is reduced, typically from contact with explosions, to zero (the damage dealt to the attacked hedgehog or hedgehogs after a player's or CPU turn is shown only when all movement on the battlefield has ceased).
