Yeah, I understand that scenario which is why I said it was great news.
For those gamers who can only have one system, by all means, it is fantastic to get the third party titles coming to the Wii U.

Unfortunately with CoD and so coming down the pipe, you run the risk of more little ones getting their hands on these mature games come birthday and Christmas time.
A lot of adults aren't savvy enough to pay attention to the ESRB ratings
