Platformers
Platformers, also called side-scrollers, view the game area from a side or "cutaway" perspective. In these games, the background or playing area smoothly scrolls as the player moves about, hence the name. These games are traditionally 2D, but some have employed 3D computer graphics effectively. Traditional elements of these games include running, jumping and some fighting. Side-scrollers were some of the first types of video games and are still popular today, usually with younger players.

Simulation
Some do not consider simulations to be games at all, but rather "digital toys" or "software toys". Indeed, this is how Will Wright, the designer of the most popular video game of all time, The Sims, describes his games. These games aim to similate a specific activity (such as flying an airplane) as realistically as practically possible, taking into account physics and other real-world limitations. Some require a great deal of reading before the game can even be attempted, while others include a simple tutorial. Some of these types of games, such as flight simulators, have a limited following, while others, such as The Sims have an enormous following, including those who don't consider themselves "gamers."
Most popular board games, card games, and the like have been computerized to some degree or another. For example, more than 600 freeware board games are available written in Zillions. Computer game programs can be worthy opponents and can help you improve your skill at traditional games.
