Video games are a very recently created medium, and are slowly becoming more common place in most cultures. Originally games were very simple computer programs that attempted to remake games that exist in real life: Pong is a computerized version of ping-pong, Tetris is a modified computerized version of a Russian puzzle game tetra (game), and the earliest computer games were probably algorithm trees based off extremely simple games like tic-tac-toe. These games were much like the early stages of cinematography, where people simply put a camera in front of a play. But eventually computers became cheaper and more common place, and the medium gradually grew into its own. Video games are now considered by some (but unfortunately, not all people) to be an art form in and of themselves. While the most popular and publicized games are often viewed as perverse orgies of sex and blood, a great deal of video games strive for high aesthetic quality, even at risk to commercial appeal. That said, even the most perverse games can have an art to their design. Ask a non-gamer what is so special about Grand Theft Auto 3 and they'll tell you it's the fact that you can go on a bloody killing spree. But most gamers know that GTA3 was special in that it allowed the player an unprecedented amount of freedom in both movement and actions (up to and including the ability to go on a bloody killing spree). Recently, video games have become a popular scapegoat in the media because of certain obscenely gorey or sexual games. But for many games, these things are only an outer layer, the real core to their design is in something called gameplay.Gameplay is, more or less, the system of rules (like gravity or range) and reactions that the player must abide by and manipulate to achieve the goals in the game. Much of the art in video games is in the gameplay, how the rules are designed, how easy it is to understand, and ultimately, whether or not playing the game is fun. This key variable is often referred to as the fun factor, as it is entirely possible for games to have a complex system of rules that is, in no way, fun or challenging to follow. Video games are different from other types of games like board games or card games in that this gameplay is not entirely known ahead of time. The players do not impose these rules and limitations on themselves, but rather, they're being controlled by a third part; the computer. This means a player can gradually (and often subconsciously) learn from trial and error, as well as observation, to ultimately understand and balance a complex system of rules that would have otherwise required them to read hundreds of pages in written instruction. But most gamers would agree that the ultimate quality and art of the experience comes from the overall blending of all aspects of the game, the gameplay, the visual aesthetics, the music, the goals, the characters, the story, and the environment.
