Copypasteo:
The ESRB advised us that it has given The Elder Scrolls Online a Mature rating. While we may disagree with the ESRB’s determination, we do not plan to challenge the rating, and we are unwilling to change the game’s content to achieve a different rating. The game we have created is the one we want our fans to be able to play.
As a result of the ESRB rating, we are in the process of promptly updating everything with the required rating and age gates, including game trailers, web sites, and ads. Thanks for your understanding. We can’t wait to welcome players into The Elder Scrolls Online soon.
Vienen a decir que a pesar de la decision tomada por la ESRB ( Entertainment software rating board), no piensan cambiar el contenido de el juego porque ahora mismo esta como querian que fuese, por lo que no van a luchar contra la ESRB para bajarles el rango de edad "permitido".

Personalmente, no se porque razon concreta les han puesto que sea +18, jugue un poco a la beta y no lo vi tan fuerte como puedan ser otros juegos.
