The Playstation 4 developed by sony is an all in one entertainment system.
It has alot of features apart from just playing games.
You can browse Wed, download many apps for free such as youtube, netflix etc. You can connect your usb hard drive and watch it on your play station.
It has a cutting edge design which makes it look cool.
it comes only in black colour but there are many skins available in the market to choose from for your console and controller.
it comes with 1 dualshock 4 controller so you might have to buy one more controller if you want to play 2 player games.
so my verdict is Go for it and let the games begin.
