Basketball is an Olympic sport that is played and enjoyed by men and women of all ages throughout the world. It can be played for fun outdoor or competitively in leagues indoor. You don't need anything to play a primitive game of basketball, other than a ball and a net or homemade contraption to shoot the basketball in. For competitive play though, you need a uniform, a good pair of shoes for solid traction, a rim, backboard and basketball net to shoot at. You can also purchase portable basket systems that allow you to set up for a game anywhere you like.
