Steam is a great platform for game distribution, but as a desktop application, it saves you the tedious task of installing games on your system. After you purchase a game, you simply click the ‘Install’ button and Steam takes care of the rest. Once the installation is complete, Steam will also take care of updating the game, and users don’t have to worry about anything but restarting the game.
Steam installs and updates game mostly in the background. Steam updates itself when you open the app and installs game updates before you open the game. Once a game is updated, you won’t be able to play it until you install the update.
