Games don't need stories.

It think Yatzee puts it best when he is referring to JRPGs "I like a game where the story and gameplay goes hand in hand. But in JRPGs, the gameplay and story are on the other sides of an iron fence....made of lions."

I prefer games to have something of a background, but many games go too far. My favorite games are the Metroid games, which have a story, but it takes a backseat to gameplay.
