Genres

A video game, like most other forms of media, may be categorized into genres based on many factors such as method of game play, types of goals, art style and more. Because genres are dependent on content for definition, genres have changed and evolved as newer styles of video games have come into existence. Ever advancing technology and production values related to video game development have fostered more life-like and complex games which have in turn introduced or enhanced genre possibilities (e.g., virtual pets), pushed the boundaries of existing video gaming or in some cases add new possibilities in play (such as that seen with titles specifically designed for devices like Sony's EyeToy

Casual games derive their name from their ease of accessibility, simple to understand gameplay and quick to grasp rule sets.

Serious games

Serious games are games that are designed primarily to convey information or a learning experience of some sort to the player. Some serious games may even fail to qualify as a video game in the traditional sense of the term. Also, educational software does not typically fall under this category (e.g., touch typing

On September 23, 2009, U.S. President Barack Obama launched a campaign called "Educate to Innovate" aimed at improving the technological, mathematical, scientific and engineering abilities of American students. This campaign states that it plans to harness the power of interactive games to help achieve the goal of students excelling in these departments.

Some of these competitions include the STEM NATIONAL VIDEO GAME COMPETITION and the Imagine Cup

.

In the early days of the industry, it was more common for a single person to manage all of the roles needed to create a video game. As platforms have become more complex and powerful in the type of material they can present, larger teams have been needed to generate all of the art, programming, cinematography, and more. This is not to say that the age of the "one-man shop" is gone, as this is still sometimes found in the casual gaming and handheld markets, where smaller games are prevalent due to technical limitations such as limited RAM

 or lack of dedicated 3D graphics rendering capabilities on the target platform (e.g., some cellphones and PDAs).

With the growth of the size of development teams in the industry, the problem of cost has increased. Development studios need to be able to pay their staff a competitive wage in order to attract and retain the best talent, while publishers are constantly looking to keep costs down in order to maintain profitability on their investment. Typically, a video game console development team can range in sizes of anywhere from 5 to 50 people, with some teams exceeding 100. In May 2009, one game project was reported to have a development staff of 450. The growth of team size combined with greater pressure to get completed projects into the market to begin recouping production costs has led to a greater occurrence of missed deadlines and unfinished products.

Downloadable Content

A newer phenomenon of withholding content from the game and then releasing it at a later date for additional funds not factored into the retail price began with digital video game distribution known as Downloadable Content (also known colloquially as 'DLC').

Other cheats might give access to otherwise unplayable levels or provide unusual or amusing features, like altered game colors or other graphical appearances.

Glitches

Software errors not detected by software testers during development can find their way into released versions of computer and video games. This may happen because the glitch only occurs under unusual circumstances in the game, was deemed too minor to correct, or because the game development was hurried to meet a publication deadline. Glitches can range from minor graphical errors to serious bugs that can delete saved data or cause the game to malfunction. In some cases publishers will release updates (referred to as patches) to repair glitches. Sometimes a glitch may be beneficial to the player, these are often referred to as exploits

For instance, take a racing game in which cars are programmed to avoid crashing, and they encounter an obstacle in the track: the cars might then maneuver to avoid the obstacle causing the cars behind them to slow and/or maneuver to accommodate the cars in front of them and the obstacle.

. Beyond such skills, which after some time become quite fundamental and are taken for granted by many gamers, video games are based upon the player navigating (and eventually mastering) a highly complex system with many variables. This requires a strong analytical ability, as well as flexibility and adaptability. He argues that the process of learning the boundaries, goals, and controls of a given game is often a highly demanding one that calls on many different areas of cognitive function. Indeed, most games require a great deal of patience and focus from the player, and, contrary to the popular perception that games provide instant gratification, games actually delay gratification far longer than other forms of entertainment such as film or even many books. Some research suggests video games may even increase players' attention capacities.

Learning principles found in video games have been identified as possible techniques with which to reform the U.S. education system. It has been noticed that gamers adopt an attitude while playing that is of such high concentration, they do not realize they are learning, and that if the same attitude could be adopted at school, education would enjoy significant benefits. Students are found to be "learning by doing" while playing video games while fostering creative thinking.

According to research discussed at the 2008 Convention of the American Psychological Association, certain types of video games can improve the gamers' dexterity as well as their ability to problem-solve. A study of 33 laparoscopic surgeons found that those who played video games were 27 percent faster at advanced surgical procedures and made 37 percent fewer errors compared to those who did not play video games. A second study of 303 laparoscopic surgeons (82 percent men; 18 percent women) also showed that surgeons who played video games requiring spatial skills and hand dexterity and then performed a drill testing these skills were significantly faster at their first attempt and across all 10 trials than the surgeons who did not play the video games first.

Whilst many studies have detected superior mental aptitudes amongst habitual gamers, research by Walter Boot at the University of Illinois found that non-gamers showed no improvement in memory or multitasking abilities after 20 hours of playing three different games. The researchers suggested that "individuals with superior abilities are more likely to choose video gaming as an activity in the first place".

Various national content rating organizations, such as the Entertainment Software Ratings Board or ESRB in North America, rate software for certain age groups and with certain content warnings. Some of these organizations are optional industry self-regulation (such as the ESRB), while others are part of national government censorship organizations. Most video games display their rating on the front side of their packaging. However, parents are not always aware of the existence of these ratings. Not all ratings are considered accurate. Organizations such as What They Play and Common Sense Media aim to provide guidance and advice for parents.
