The ESRB (which stands for "The Entertainment Software Rating Board") rates video games in North America. It was established by the IDSA (The Interactive Digital Software Association), and is now known as the ESA (The Entertainment Software Association).
I've read that several major game developers, such as Vivendi Universal and id Software, recently left the IDSA/ESA. Does that mean that their post-ESA departure games will no longer be rated through the ESRB? Will their games be rated at all anymore?
