We can define the game as a physical or psychical activity of leisure subjected to rules. People play games to have fun and to get some pleasure of this amusement. For many scientists Mankind is the only species to play games and it is, with laughter, unique to mankind.

There have been many definitions of a game, but none seem to satisfy every one. This is why people agree on some key components that define a game, there must be a goal (winning most of the time), some rules, a challenge and some interactivity. This is why there are many completely different games, changing according to the rules, and the components of this game. Indeed, a game can be played bare hands, or you sometime need a complete set of things to play it.

The video games are the next generation of games. Indeed, those games often are real existing games transcribed in a virtual environment but it can also be completely original games that have never been created before.

The most famous video games are the Super Mario Series, the Metal Gear Solid series, the Resident Evil series and many others as the Madden NFL series.
