Asteroids is a space-themed multidirectional shooter arcade video game designed by Lyle Rains and Ed Logg released in November 1979 by Atari, Inc. The player controls a single spaceship in an asteroid field which is periodically traversed by flying saucers. The object of the game is to shoot and destroy the asteroids and saucers, while not colliding with either, or being hit by the saucers' counter-fire. The game becomes harder as the number of asteroids increases.
Real-time strategy (RTS) is a subgenre of strategy video games that does not progress incrementally in turns, but allow all players to play simultaneously, in "real time." By contrast, in turn-based strategy (TBS) games, players take turns to play. The term "real-time strategy" was coined by Brett Sperry to market Dune II in the early 1990s.
In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program was originally designed for. The term is also used when software/hardware is changed to make them usable in different environments.
M.U.L.E. is a multiplayer video game written for Atari 8-bit computers by Ozark Softscape. Designer Danielle Bunten Berry takes advantage of the four joystick ports of the Atari 400 and 800 to allow four-player simultaneous play. Published in 1983, M.U.L.E. was one of the first five games from new company Electronic Arts, alongside Axis Assassin, Archon: The Light and the Dark, Worms?, and Hard Hat Mack. It is primarily a turn-based strategy game, but incorporates real-time elements where players compete directly as well as aspects that simulate economics.
Danielle Bunten Berry, was an American game designer and programmer, known for the 1983 game M.U.L.E., one of the first influential multiplayer video games, and 1984's The Seven Cities of Gold.
Strategic Simulations, Inc. (SSI) was a video game developer and publisher with over 100 titles to its credit from its founding in 1979 to its dissolution in 1994.

The Seven Cities of Gold is a strategy video game created by Danielle Bunten Berry and Ozark Softscape and published by Electronic Arts in 1984. The player takes the role of a late 15th-century explorer for the Spanish Empire, setting sail to the New World in order to explore the map and interact with the natives in order to win gold and please the Spanish court. The name derives from the "seven cities" of Quivira and Cíbola that were said to be located somewhere in the Southwest United States. It is considered to be one of the earliest open world video games.
Tactical role-playing games, also known as strategy role-playing games and in Japan as simulation RPGs, are a video game genre that combines core elements of role-playing video games with those of tactical strategy video games. The formats of tactical RPGs are much like traditional tabletop role-playing games and strategy games in appearance, pacing, and rule structure. Likewise, early tabletop role-playing games are descended from skirmish wargames such as Chainmail, which were primarily concerned with combat.
Turn-based tactics (TBT) is a video game genre of strategy video games. They are turn-based simulations of operational warfare and military tactics in generally small-scale confrontations as opposed to more strategic considerations of turn-based strategy (TBS) games. Turn-based tactical gameplay is characterized by the expectation of players to complete their tasks using only the combat forces provided to them in a generally realistic manner.
Computer Quarterback is an American football simulation video game written for the Apple II by Danielle Bunten Berry and published in 1981 by Strategic Simulations.

A tile-based video game, or grid-based video game, is a type of video game where the playing area consists of small square graphic images referred to as tiles laid out in a grid. That the screen is made of such tiles is a technical distinction, and may not be obvious to people playing the game. The complete set of tiles available for use in a playing area is called a tileset. Tile-based games usually simulate a top-down, side view, or 2.5D view of the playing area, and are almost always two-dimensional.
Legionnaire is a computer wargame for Atari 8-bit computers created by Chris Crawford released through Avalon Hill in 1982. Recreating Julius Caesar's campaigns in a semi-historical setting, the player takes command of the Roman legions in real-time battles against the barbarians.
Tower defense (TD) is a subgenre of strategy games where the goal is to defend a player's territories or possessions by obstructing the enemy attackers or by stopping enemies from reaching the exits, usually achieved by placing defensive structures on or along their path of attack. This typically means building a variety of different structures that serve to automatically block, impede, attack or destroy enemies. Tower defense is seen as a subgenre of real-time strategy video games, due to its real-time origins, even though many modern tower defense games include aspects of turn-based strategy. Strategic choice and positioning of defensive elements is an essential strategy of the genre.
A computer wargame is a wargame played on a digital device. Descended from board wargaming, it simulates military conflict at the tactical, operational or strategic level. Computer wargames are both sold commercially for recreational use and, in some cases, used for military purposes.
Strategy is a major video game genre that emphasizes thinking and planning over direct instant action in order to achieve victory. Although many types of video games can contain strategic elements, as a genre, strategy games are most commonly defined as those with a primary focus on high-level strategy, logistics and resource management. They are also usually divided into two main sub-categories: turn-based and real-time, but there are also many strategy cross/sub-genres that feature additional elements such as tactics, diplomacy, economics and exploration.
