What if Pokemon X and Y were rated higher than E (Or the equivalent in your area)? I know Pokemon has been rated E since the beginning but I believe Game Freak should make the games more mature for older fans. The number of older fans has increased and I think Game Freak should realize this. Also, children would still buy it. Have you seen how many 10-year olds buy M rated games? The anime could go a different route but that's besides the point.
EDIT: Is it* possible that Pokemon X and Y will be rated something higher than E?
And just so you know, I am hoping for more complex story lines (That childeren wouldn't understand.) and perhaps a little bit more fantasy violence but, none of that M-rated or T rated stuff, just as high as E 10+.
