I hope the new translation is more accurate because it certainly makes more sense.
Right now, the Wii U does not offer enough diversity. The aesthetics are very one-sided. More of the same will only attract--that's right--the same people who already own a Wii U. Bayonetta 2 and X are coming, sure, but they might be too little, too late.
I wouldn't say that Nintendo has been too focused on children but rather that the Wii U's offerings have been too one-dimensional.
