(Update: Hatred is Out. Reviews in. Déja Vu.)Are “M” Rated Games Really Mature?

[Skullwaker]

In this case, mature =/= deep and intellectual. It just means blood/gore/sex/swearing/all of the above.

Just a way for parents to be careful when shopping for their kids and for store employees to stop younger gamers from buying stuff out of their age group (though this isn't always the case).
