I think twelve or thirteen years old can and CAN NOT be able to play video games that they want. Because base on all the boys in my class, most of them play games that violent a lot but all the girls in my class, they don't.
Girls usually play games that have cute graphics, colorful, fashion, ect. Example like,
- Mario games =>> it about rescue the princess.
- Fashion games =>> girls usually go shopping because they like dress, shirt, skirt, jewelry, ect.
- Games on facebook (Pet society) =>> almost of the animals in there are seem to be cute graphics.
But the boys usually play violent games because they like to challenge,they think that is fun =.=" and when they are angry, they want to relieve angry by play violent games or smack the other persons =]]. For example,
- Smack down =>> it about fighting the others. I have seen that and i have to reallize that those people play that "game" was so SEXY =]] and they are so violent. I remember that, one time, John Cena something (i don't know how to spell his name) was broke his neck because of fighting. I'm scare!!!
So, you see that, almost of the boy play too many violent video games and that is not good because it might affect their mind, their thought, and THEIR ACTIONS either. They might imitate those player ans that won't be good. But if they play games for example like tic-tac toe, sudoku, some kind of games that "force" them must use their brain to think, that will be really useful for them because their mind will be clever, their thought will be judicious, and their action will be very active. And that will be also very good.
That's the reason, why, i think twelve and thirteen year old can and can not be able to play video games that they want.
