Or so I gather, since they sent me a press update with the updated box art now that they have received their ESRB rating.
The alternate title for this post: Tanks for Teens.
Having played the game, the teen rating seems a bit much. The description for the Teen rating says:
Contains content that might be considered unsuitable for children under 13 years of age. Titles in this category may contain more intense violence, suggestive themes, crude humor, blood, simulated gambling, and/or use of strong language (which is uncensored)
I wonder what prompted the ESRB to choose that rating as part of their process? That is the same rating as WoW, EverQuest II, Lord of the Rings Online, and most other MMOs I looked up where your avatar personally hacks humanoids to death. In World of Tanks, it is just vehicles getting knocked out.
Or maybe online games just get Teen by default due to the chat channel.
