Sighs, whether it be video games, movies, tv shows, or even watching YouTube, parents just do not seem to want to be the one's taking responsibility. Where they'd rather blame others, or even the companies who make the games, then be the one to actually parent their own children. Where it always frustrated me how so many parents did not care what games their child plays, until it becomes a problem and then they show outrage for the game itself.
I think the gaming market is getting so big every year that it's getting harder to "Control" what are the age's demography for each group.
Also, I don't think I would've had motor skills to play Call of Duty at seven years old *laugh* I was stuck with Sonic.
I believe gaming age does matter, and a big part of it is if you are mature enough in both age and wisdom to understand what the game even is. Many kids are given free reign with things they have no clue about, which I believe is what leads to the problems. I think games are a good way to boost a kid's learning pace if educated about them properly.
