Why do some games require the compass when they don't use it?

Examples: Disney Hidden Worlds, and some of the Lego Star Wars games...

As far as I can tell, they don't actually USE the compass for anything, yet they require it!

This doesn't affect me as I have an iPhone, but I know someone with an iPod Touch who wants to play these games...

It's kinda like how some games require a front facing camera.

It's probably to make sure that you can't install the game on a device which isn't powerful enough to run the game.
