Just like everyone else has said, this game is definitely not directed more towards kids than any of the other games. Although, I will say this, the game was easy. Like, REALLY easy. I don't know if I've just gotten really good over the past... oh... 13 years is it now? But I was able to defeat the E4, Ghetsis, and N, with my highest pokemon being a level 44 Beartic. The fact that this game actually features a somewhat complex plot though, definitely means that the plot parts aren''t geared towards children, because even now, there were some parts that confused me, and I don't think little kids would understand the ulterior motives of Ghetsis.
Of course, I must also mention the competitive scene. With all the EV's and stuff, I'm pretty sure any young children wouldn't be able to win a single online battle, because even thoguh your Venusaur is level 100, cut, leech seed, solar beam, and mega drain, is not a good moveset, and 252 speed EVs won't do it much good :P.
Overall, I think the game is just as directed toward children as its always been.
