How do you play games

That my friend is a VERY long subject depending on which type of games your talking about ;PC,console..... But to sum it up the 2 main games are either PC games or Console games (then it branches out to handheld,cellphone and others) To play a PC game you use

~Keyboard and Mouse
~And if its allowed by game a Joystick or usb Controller

For a console-

~Controller (Which varies from game to game, like for a PlayStation console its a DualShock Controller.

To get both console and PC games you can buy it from a game shop (like Gamestop,EA Games,...)

For PC it is possible to buy it from legal applications like Steam or illegally by some sites.
