One of the most important parts of a video game system is the cell processor
because the cell processor is what makes the graphics look so good for the
Playstation 3.The Playstation 3 has a DVD player and it also can play DVD-r
(which is something that you burn off of your computer). The controllers for
the Playstation 3 are different from the Playstation 2 controllers because the
Playstation 3 controllers have a USB port in the middle of the controller. The
Playstation 3 controllers are called a dual shock 3 controllers. Dual shock
controllers are just controllers with more buttons added into them and, if you
don’t know where the extra button is on the controller I will tell you. If you
press down on the left or right analog stick, you will find the buttons. The
buttons are called L3 and R3.

Some things that are different than the Playstation 3 is the system itself
because the Playstation 2 only comes in one color, which is black, but the
Playstation 3 comes in three colors: black, white and silver. The games for
the Playstation 2 and 3 are very different because they only have the newer
games for the newer systems. For example, NBA Street Home Court and
Grand Theft Auto IV were made for the Playstation 3. These games cannot
be played on a Playstation 2. I think this is because the Playstation 2 cannot
handle the graphics in these games. Those are some ways how video games work.
