     "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.")

You control a secret organisation charged with defending Earth from a brutal

alien enemy.  Build up your bases, prepare your team, and dive head-first into
 | 
						||
the fast and flowing turn-based combat.
 |

Over the long term you will need to conduct research into the alien threat to

figure out their mysterious goals and use their powerful weapons for your own
 |

ends.  You will produce unique items and use them in combat against your
 |

enemies.

You can also use them against your friends with the multiplayer functionality.

Exult is fully compatible with the original Ultima 7, but doesn't require any

     "In Widelands, you are the regent of a small clan.  You start out with
 | 
						||
nothing but your headquarters, where all your resources are stored.
 | 
						||
 | 
						||
In the course of the game, you will build an ever growing settlement.  Every
 | 
						||
member of your clan will do his or her part to produce more resources---wood,
 | 
						||
food, iron, gold and more---to further this growth.  The economic network is
 | 
						||
complex and different in the five tribes (Barbarians, Empire, Atlanteans,
 | 
						||
Frisians and Amazons).
 | 
						||
 | 
						||
As you are not alone in the world, you will meet other clans sooner or later.
 | 
						||
Some of them may be friendly and you may eventually trade with them.  However,
 | 
						||
if you want to rule the world, you will have to train soldiers and fight.
 | 
						||
 | 
						||
Widelands offers single-player mode with different campaigns; the campaigns
 | 
						||
all tell stories of tribes and their struggle in the Widelands universe!
 | 
						||
However, settling really starts when you unite with friends over the Internet
 | 
						||
or LAN to build up new empires together---or to crush each other in the dusts
 | 
						||
of war.  Widelands also offers an Artificial Intelligence to challenge you.")

missions, equipment, and ships; even the galaxy itself grows larger

that it can be wrapped in CGI scripting, PHP, and the like to allow people

to play games on webpages.  It can also be made into a chat bot.")

In this game, you play as a manager of a theme park, allowing you to make a

park of your dreams.  The list of responsibilities includes managing staff,

finances, landscaping, and most importantly: rides.  Good managers follow the

principle of prioritizing the guests' happiness with a well-maintained park.

Should they go unwise, a theme park plunge into chaos with vandalizing guests
 |

and unsafe rides.  Which path will you take?")
