The purpose of the game is for the characters actions to affect and change the world.The quickest way for players to get involved in a world is realizing things they do will have meaning within that world.
Conversely, the quickest way for players to be apathetic of a world's existence is if/when they catch on nothing they do will actually make any real difference because the DM is too overprotective of "his" world.
My games are always epic with characters that alter the setting.
My previous campaign saw the characters save their world by resurrecting a dead prime world through a massive ritual.
I create the setting and story hooks and then the events and world are the playground of the characters.
