Multi-user dungeonA MUD (mʌd; originally multi-user dungeon, with later variants multi-user dimension and multi-user domain) is a multiplayer real-time virtual world, usually text-based or storyboarded. MUDs combine elements of role-playing games, hack and slash, player versus player, interactive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, and non-player characters, and perform actions in the virtual world that are typically also described.
Timekeeping in gamesIn video games and other games, the passage of time must be handled in a way that players find fair and easy to understand. This is usually done in one of the two ways: real-time and turn-based. Real-time strategy and Real-time tactics Real-time games have game time progress continuously according to the game clock. One example of such a game is the sandbox game Terraria, where one day-night cycle of 24 hours is equal to 24 minutes in real time. Players perform actions simultaneously as opposed to in sequential units or turns.
RoguelikeRoguelike (or rogue-like) is a subgenre of role-playing computer games traditionally characterized by a dungeon crawl through procedurally generated levels, turn-based gameplay, grid-based movement, and permanent death of the player character. Most roguelikes are based on a high fantasy narrative, reflecting their influence from tabletop role playing games such as Dungeons & Dragons.
Non-player characterA non-player character (NPC), or non-playable character, is any character in a game that is not controlled by a player. The term originated in traditional tabletop role-playing games where it applies to characters controlled by the gamemaster or referee rather than by another player. In video games, this usually means a character controlled by the computer (instead of a player) that has a predetermined set of behaviors that potentially will impact gameplay, but will not necessarily be the product of true artificial intelligence.
Tile-based video gameA tile-based video game is a type of video or video game where the playing area consists of small square (or, much less often, rectangular, parallelogram, or hexagonal) 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.
Text-based gameA text game or text-based game is an electronic game that uses a text-based user interface, that is, the user interface employs a set of encodable characters, such as ASCII, instead of bitmap or vector graphics. All text-based games have been well documented since at least the 1960s, when teleprinters were interlaced with mainframe computers as a form of input, where the output was printed on paper.
Space flight simulation gameA space flight simulation is a genre of flight simulator video games that lets players experience space flight to varying degrees of realism. Common mechanics include space exploration, space trade and space combat. Some games in the genre aim to recreate a realistic portrayal of space flight, involving the calculation of orbits within a more complete physics simulation than pseudo space flight simulators. Others focus on gameplay rather than simulating space flight in all its facets.
Vehicle simulation gameVehicle simulation games are a genre of video games which attempt to provide the player with a realistic interpretation of operating various kinds of vehicles. This includes automobiles, aircraft, watercraft, spacecraft, military vehicles, and a variety of other vehicles. The main challenge is to master driving and steering the vehicle from the perspective of the pilot or driver, with most games adding another challenge such as racing or fighting rival vehicles.
