Rollergames is a coin-operated arcade game by Konami, made in 1990, and based on the television show of the same name. Score values are cut in half from the real show (and rounded up if needed), and feature only four 99-second cycles instead of 45-second cycles within four 6-minute periods. The players control the two jetters. After referee Don Lastra blows his whistle to begin the cycle, the first lap leads the jetters to the Wall of Death (the heavily banked curve of the jetwave). They get one point for getting three steps in the between the two red lines and three points for getting above the top line. On the jet jump, they get three points for landing beyond the 12-foot marker and one point for landing in front of the line. The rest of the cycle awards one point passing or fighting off opposing blockers (who come back to haunt the jetters afterwards) and three points for lapping or fighting off the opposing jetter. The team with the most points wins. While it doesn't affect the score of the game (only awarding a small amount of "power" to the winner), there is a bonus Street Fighter II style fight that may happen to illustrate the violence and rivalry that happens on RollerGames.

The game is essentially a series of 36 jigsaw puzzles with Tetris-like pieces known as pentominos that must be assembled into a specific shape. The puzzles start off with rectangular shapes and simple solutions, but the puzzles quickly grow more complex, with odder shapes like a rocket ship, a gun, and even enlarged versions of some of the pentominoes themselves. Each level is timed, and once the timer is started it cannot be stopped until the level is finished. One starts off the game with only three pentomino pieces, and at the completion of each early level, a new piece is awarded to the player. At the final level, the player is given the 2x2 square O tetromino and must complete an 8x8 square puzzle. After completing each level, the player was given a password to access that level at a later time. Interestingly, each password was a common English four-letter word, so that by guessing common four-letter words, players could potentially access levels they had not actually reached by playing the game.

The player controls an armoured fighting vehicle from either a first-person perspective or a third-person perspective; depending on the level design. All games begin on a planet's surface with an overhead view. When the player enters a tunnel, the view switches to first-person. After destroying the Life Core inside a tunnel, the player travels to a new planet through a vertically scrolling stage. Cosmo Tank has three modes. In quest mode, the object of the game is to destroy Alien Life Cores on five planets to free them from Master Insect. Players can earn experience levels in the quest mode by defeating enemies. The maximum amount of experience points that a player can earn is 999; which allows players to reach the level cap of 6. In training mode, the player practices in a closed area and is given a ranking. In vs. mode, the Game Link Cable is used to allow two players to race to defeat the alien leader. After either beating the game or acquiring a game over, the player is given a rank that shows how far he made it in the game along with his target score. The lowest rank in the game is a skull and crossbones (signifying a casualty on the battlefield).

Commander Keen is the first truly "commercial quality" game to be distributed as shareware. It features ultra-high-speed smooth-scrolling EGA graphics and superb sound effects. The animation and scrolling is updated at nearly 40 frames per second, for comparison, motion picture quality cartoons are filmed at only 24 frames per second.

You play the role of Billy Blaze, an eight-year-old kid genius who builds an interstellar ship when not working at home on his college fast-track degree. Among other household objects, Billy uses his Nintendo joystick for flight control and his mom's vacuum cleaner (heavily modified) for his ship's ion propulsion system (with pile height adjustment).

So Octopus sets out on a search for the truth and with his companions begins to travel the world!

Released a few years after its original creation, John Carmack's earliest written game is a fantasy RPG somewhat inspired by the early Ultima games. The story takes you to the peaceful town of Jaterus, about to become much less peaceful thanks to one Greymere. This evil archmage has taken up residence in a three-level dungeon, conveniently located just outside the city walls. More alarmingly, he has constructed the Shadowforge - a potent magical artifact that has enhanced both his power and ambition for conquest; Jaterus is first on his list. Your job is to quash his aspirations by finding and destroying the device. The town of Jaterus is your base of operations, its main attractions being the weapon and armor shops, the inn (where you can recuperate after a sojourn to the dungeon), the temple (where health potions are sold), and the tavern (which, besides refreshments, offers conversation - some of it helpful). The various random NPCs do not communicate, though. The dungeon is populated by Greymere's minions; some are randomly placed, others are not, and all must be bested in turn-based combat - the deeper you go, the tougher the bad guys. Fighting involves both melee and ranged attacks, and defeated monsters will bequeath both gold and experience. Leveling up will increase your maximum hit points, but no other stats are tracked. Some secrets await to be revealed along the way, too.

Commander Keen is a series of side-scrolling platform video games developed primarily by id Software. The series consists of six main episodes, a "lost" episode, and a final game; all but the final game were originally released for MS-DOS in 1990 and 1991, while the 2001 Commander Keen was released for the Game Boy Color. The series follows the titular Commander Keen, the secret identity of the eight-year-old genius Billy Blaze, as he defends the Earth and the galaxy from alien threats with his homemade spaceship, rayguns, and pogo stick. The first three episodes were developed by Ideas from the Deep, the precursor to id, and published by Apogee Software as the shareware title Commander Keen in Invasion of the Vorticons; the "lost" episode 3.5 Commander Keen in Keen Dreams was developed by id and published as a retail title by Softdisk; episodes four and five were released by Apogee as the shareware Commander Keen in Goodbye, Galaxy; and the simultaneously developed episode six was published in retail by FormGen as Commander Keen in Aliens Ate My Babysitter. Ten years later, a homage and sequel to the series was developed by David A. Palmer Productions and published by Activision as Commander Keen. Invasion of the Vorticons was the only game developed by Ideas from the Deep, and was based on programmer John Carmack's creation of adaptive tile refresh, a technique that allowed IBM-compatible general-purpose computers to replicate the smooth scrolling of video game consoles such as the Nintendo Entertainment System. The game's success caused designer Tom Hall, programmers John Carmack and John Romero, and artist Adrian Carmack to found id Software. Their obligations to Softdisk, where they had worked during development of the game, led to the creation of Keen Dreams as a prototype for the second trilogy of episodes. The final episode was split off during development into a stand-alone retail title, and plans for a third trilogy were cancelled after the success of Wolfenstein 3D (1992) and development focus on 3D first-person shooters such as Doom (1993). The final Keen game ten years later had oversight but little development work from id. Critical reception and the series' legacy has focused on the two main trilogies of episodes, with Vorticons having large success as a shareware game and impacting the success of Apogee (now 3D Realms) and its shareware model. The second trilogy sold fewer copies, which was blamed by id and Apogee on its split into two parts, and the 2001 game received mixed reviews. The MS-DOS games have been re-released in several compilation packages, and all but the sixth episode are still sold through modern emulation releases on platforms such as Steam. References to the series have been made by dozens of other games, especially to the Dopefish, an enemy in the fourth episode, which has been termed one of the video game industry's biggest in-jokes. An active modding community has grown around the series, producing editing tools and unofficial sequels.

The first game in Nichibutsu's Formula One top-down racing series. F1 Circus is a top-down Formula 1 racing game and the first game in Nihon Bussan's F1 Circus series. It was first released on the PC Engine in 1990, but a modified version - also partially based on this game's sequel, F1 Circus '91 - would later be released on the Famicom in 1992. As with every other game in the series, the game was never localized in North America or Europe. The game uses the real life names of drivers and teams from Formula 1, like Nigel Mansell and Ferrari. The series would continue to acquire the various licenses needed to use real names from Formula 1.

Stunts (also known as 4D Sports Driving) is an early 3D racing video game developed by Distinctive Software, Inc.. The game places emphasis on racing on stunt tracks and features a track editor, it is clearly influenced by the earlier arcade game Hard Drivin' and has many similar elements to the game Stunt Driver which was released around the same time. In Stunts, players race a lap around the circuit, with the aim of completing the lap as quickly as possible without crashing. However, these laps often feature special track areas such as loops, jumps (including over tall buildings), slalom roads and corkscrews. The game area is restricted by a large fixed size square area defined and surrounded by a fence which the game is designed to prevent the player from leaving. Players can either race against the clock or choose between six different opponents; there is no support for real-time multiplayer. Stunts features 11 different drivable cars, with either automatic or manual transmission. Replays of races can be saved and reviewed. There are four camera views available during replay and actual driving, and the dashboard is an optional overlay on all views. It is also possible to continue the race from any point in the replay, however the time for that race will not be recorded. Another major feature of the game is the built-in track and terrain editor which allows the user to design arbitrary new tracks or modifications of existing tracks.[2] The cars can drive on paved roads, gravel roads, icy/snow roads, and grass if driving off the track — which all offer different levels of grip. The game has a relatively advanced pseudo-physics engine for its time which can simulate oversteer and understeer, grip is also proportional to the banking of a curve. The game features a 3D engine with flat shading and no textures, it uses polygonal graphics for most objects, including trees and road signs, there are few sprites. The resolution is 320×200 with 256 colors. There is an option to select high and low detail. The game is written for DOS and executes in real mode.[3] Stunts includes a form of copy protection. Each time after running the program, players must complete a specific phrase found in the game manual before being allowed to race. If the player fails to complete the phrase three times, the next race will still load. However, approximately four seconds into the race, the player is informed that he or she did not deactivate the car's security system, the car crashes, and the player is returned to the main menu.
