XBOX Updates Question

I don't own an X box, but assuming the basic idea works like the PS3, the games should update themselves. i.e. when they say they need an update, you say ok and watch it download and install.

If you try to find updates for X-box 360, it's probably looking for updates to the overall system, which is not what your games are telling you.

Just load the game and follow the prompts.

Or, I'm completely wrong.
