If they don't know the game commands, they need help- hence "help" would make sense to most.
It ain't tech support, what else could "help" be? Send you a free beer with a hot female super model when you click it?
Only if it did....
EDIT: most people are just too lazy to bother with a manual anyway. Even in box games that come with manuals, people ask you how to do things that are covered in the manual! People are lazy, you could only get them to read the help files if you paid them to.
