Imagine a place of wonder,where magic and technology hold equal sway, and an adventurer might just as easily wield a flintlock pistol as a flaming sword. A place where great industrial cities house castle keeps and factories, home to Dwarves, Humans, Orcs and Elves alike. A place of ancient runes and steamworks, of magic and machines, of sorcery and science. Arcanum is the first game to come from the development house Troika Games, LLC, started by former Fallout team members Tim Cain, Leonard Boyarsky, and Jason Anderson. This team takes the depth of gameplay and world-building in role-playing games to entirely new levels of realism and excitement. Arcanum creates a compelling new world where magic and technology coexist in an uneasy balance. As Arcanum opens, the mechanical age has only recently arrived in this ancient land where Humans, Elves, Dwarves, Orcs and other races have learned to survive in the new sprawling industrialized cities. But this radical shift from magic to technology has created a potentially explosive situation. As the townspeople and other thinkers begin mass production of light bulbs, batteries, eyeglasses and guns, the Mages grow leery. This tightly wound setting is the starting point from which the character must set out on his quest.

To simulate realistic police procedures, SWAT 4' encourages the use of non-lethal force to subdue and arrest subjects rather than incapacitating or killing them. In addition, players must follow strict protocol to ensure proper use of force. Players may not fire on suspects with lethal weapons unless the suspect points their firearm at a fellow officer or a civilian. Penalties are given for unauthorized use of force, injuries to hostages, officer incapacitation, and personal injury. On the higher difficulty levels, more points are required to pass the mission, with 100 being perfect. On the most difficult level, Elite, players need a 95/100 to pass, and will fail for killing even a single suspect, losing more than two team members without committing an infraction, or committing any infraction in addition to being injured.

Ground Control is set in the 25th century. Mankind emerged from the devastation of the Third World War (known in the game as "The Sixteen-minutes War", which almost wiped out the whole of humanity) and managed to colonize several planets across the galaxy. The Earth is ruled by a council called GCC (Global Central Command) that is formed by elected representatives and representatives of the mega corporations which rose to power after the fall of the Terran nations. The game's plot revolves around the conflict between the Crayven Corporation and the Order of the New Dawn for the possession of the distant world of Krig 7-B. In the beginning of the game, the player assumes the role of Major Sarah Parker of the Crayven Corporation as she leads the Crayven forces in order to eliminate the presence of the "Dawnies" (her derogatory nickname in reference to followers of the Order). In the second campaign, the player assumes control of Deacon Jarred Stone in his attempt to drive the "Crays" from the surface of Krig 7-B. During the course of the campaign, however, both characters unravel a dark secret hidden within the depths of the planet, a secret that threatens all mankind, and turns out to be the reason for such interest in what seems to be a desolate fringe world.

Caesar III is part of Sierra's City Building Series and was released in October 1998. Cities in Caesar III try to accurately reflect the life of Roman citizens: the lowest plebians live in tents and shacks, while the richest patricians live in villas. Staple foods include wheat, fruits, vegetables, and pork, and wine is required for some festivals and houses. Citizens wander the streets in their various garbs and can tell the player their name and how they feel about the city. The city is viewed in a two-dimensional isometric view with a fixed magnification level and can be rotated ninety degrees. Access to services such as market goods, entertainment, hygiene, education, and taxation are represented by "walkers," people sent out from their buildings to patrol the streets. Any house that a walker passes is considered to have access to the services of the walker's building. All movements of goods and coverage of walkers are accurately reflected by citizens walking the streets: a player can watch a farm's crop progress, and when it's ready, a worker will push a full cart from the farm to a nearby warehouse or granary; then return with an empty cart. Background music is played, which varies according to the situation (gentle themes to begin with, war drums during times of conflict and triumphal music when the player nears the objective). Crowd noises supplement musical themes, the sounds of manufacturing and the clash of weapons at appropriate times. There are two ways to play the game: Mission Mode, which is equivalent to the typical "campaign" modes of other strategy games, and City Construction Mode, in which the player plays one scenario from scratch.

Half-Life: Uplink is a demo version of Valve's 1998 first-person shooter computer game Half-Life. Uplink features many of the common enemies, characters, and weapons from the full game, but unlike the first Half-Life demo and the Half-Life 2 demo, the location and scenario in this demonstration do not appear in Half-Life. The Uplink chapters were cut during Half-Life's development phase and roughly fit in prior to or during the Lambda Core chapter; they were, however, strongly revised for the demo release. Uplink also includes the same Hazard Course from the full release of Half-Life. It was also included on "Official PlayStation Magazine Disc 57" as a bonus unlock if you entered a cheat into the PS2 version of Half-Life and swapped the discs.

Epochs are the ages a player passes through in Empire Earth. Each of these epochs represents an age within history. In Empire Earth, the last two ages (Digital and Nano Ages) are set into the moderate future. In the Art of Conquest, a third future age, the Space Age, is available. It deals with space colonization. Each epoch brings new technologies and units. Epoch advancement requires additional buildings to be built and the costs of advancing increases as more epochs are attained, although the ability to gather the required resources greatly increases as well. With new epochs, some new units are available at the cost of having to abandon the ability to produce old units, though any old units still alive are kept. The epochs in Empire Earth are the Prehistoric Age, the Stone Age, the Copper Age, the Bronze age, the Dark Age, the Middle Ages, the Renaissance, the Imperial age, the Industrial age, the Atomic World War I age, the Atomic World War II Age, the Atomic Modern Age, the Digital Age and the Nano Age. An extra epoch, the Space Age, is available in Empire Earth: The Art of Conquest.
