What do the various ESRB ratings mean?
From the ESRB site: The Entertainment Software Rating Board (ESRB) ratings are designed to provide concise and impartial information about the content in computer and video games so consumers, especially parents, can make an informed purchase decision. Games2U offers a range of games. These ratings are listed here (link). Please contact your game coach any time prior to your party if you wish to limit the games offered at your party to one rating or another.
