Sony's PlayStation 2 is the most popular video game system in the world today. Sony first built its reputation on the original PlayStation, which took the gaming community by storm. The PlayStation was released at approximately the same time as the Nintendo 64. The Nintendo unit opted again to use cartridges, while the PlayStation used CD-ROMs. While the Nintendo was a fine console, the PlayStation represented the wave of the future, especially as evidenced by today's game consoles, all of which use some form of disc.

When a person purchases a PlayStation 2, it comes with one controller for PS2 games. While this is all that is needed to play, for most gamers, one controller won't be enough. The PlayStation 2 has two controller ports (and can be upgraded to four), so to play with friends, another controller for PS2 will be needed. Many gamers also prefer to use wireless controllers, since they are more freeing and less obtrusive.

When purchasing an additional controller for PS2, there are a few options available. While any PS2 controller will get the job done, there are higher-end controllers that some gamers may prefer. These controllers will differ in size and sometimes sensitivity, but there's not too much of a difference. Most if not all controllers have motors for vibration. For many games, this vibration effect aids greatly in gameplay by alerting players when their characters are being attacked or something similar.

Other games may require different types of controllers as well. For a racing game, a driving wheel can make the game not only more enjoyable, but it can also make the gameplay more realistic as well. For the hugely popular Dance Dance Revolution game, there's also a dance pad that may be hooked up to the console.
