US age ratings body ESRB has said it won't follow PEGI's example in Europe and begin factoring in elements like paid random items when determining the age rating for a game.
Speaking to The Game Business, ESRB said that following PEGI's lead could be "confusing" for parents.
As such, there are currently no plans for ESRB to allow any factors outside of the content and context of a game to influence the age rating assignment.".
PEGI director general Dirk Bosmans, in response, said: "We're conscious of the concerns that ESRB voices.
But by integrating them both into an age rating, you have to be mindful that you may not be able to give all the levels of detail that you gave beforehand.
PEGI's changes come into effect in June, so only after that point will we see games rated under the new criteria.
Many previously released games will continue with their existing age rating, but PEGI has confirmed - if it needed confirming - that ongoing live service games will be reappraised. »
