The inverted control argument can go either way. For those accustomed to playing with inverted controls (like myself), regular controls guarantee a premature death; especially in demos, when they are set to regular by default. Do your friends a favor: always notify them of your setting when handing the controller over to them before they try to play and fail miserably.
If you or your friends are still not convinced of the dangers of inversion vs. non-version, then watch how this predicament can play out in a real life situation.
There used to be an embeded media player here, but it doesn't work anymore. We blame the Tumbeasts.
