You're assuming that you always want to save. It's possible that the reason someone is quitting is because there's been some type of issue and the player may not want to save the game as is. If you're going to automatically save, then you better save to another save file so that a previous save can always be loaded. You wouldn't want your only save to be of an unstable gamestate.

Reply to Rant: All single player games should have an easy way to quit to desktop and save as-is. Too many games require exiting to main menu and then quitting from there -- with an obligatory "ARE YOU SURE - YOUR PROGRESS WILL NOT BE SAVED" warning. Save the progress and quit -- it's not that hard. by BBorNot
