I'm simply here to say that Common Sense Media is 100% off with their review of Grand Theft Auto V. First off, the summary.
GTA V is set in a modern day recreation of Los Santos, a parody of Los Angeles. You play as a trio of criminals: Michael de Santa, a retired con-man trying to pull of one last set of heists to set him and his friends for life; Franklin Clinton, a "2-bit gangster gone 3-bit," and trying to make it big; And Trevor Phillips, a maniac, business owner, and Michael's old partner. These three men work together to pull of the heists that will set them for life.
Now, to state the truth against Common Sense.
Positive Messages. CS claims that there are NO positive messages, but I beg to differ. The game is all about choices, and living with those choices. For instance, Franklin becomes friends with Michael and his family, and Trevor. In the last mission, he must choose between killing of the main antagonist, or killing Michael, or killing Trevor. Whatever he chooses, he must live with the consequences that that choice brings, such as how his friend react. And those choices will bring about great changes to the games.
Another instance is that Michael faked his death in the beginning of the game, and wouldn't tell Trevor how he did it, or why. In one of the later missions, this drives Trevor to (further) insanity, and drives the friends apart, making them cold and distrustful. This shows the harm that keeping secrets from friends will do.
Positive Role-Models. While you may not want to take Trevor as your role model, Franklin and Michael are actually very positive characters. Franklin is extremely loyal, and open-minded towards everything. He protects his friends through thick and thin, and is always there to break Trevor and Michael apart in case they begin to fight. He's a reliable man, and someone who models themselves after that would be a good person to know.
Michael, on the other hand, brings forth the side of a family man. Earlier in the story, his family pretty much hates him. His wife, Amanda, cheats on him. His daughter, Tracey, rebels against him. His son, Jimmy, ignores him. Eventually, they all leave him, and Michael does everything in his power to get them back in his life. After he does everything he can to protect them, and they now realize that's what he was doing all along, he continues to prevent anything else from happening to them. He also tries to patch things up between him and Trevor, and does what he can to make Franklin feel like he has a home with the de Santas. He's friendly, caring, and protective, and another good man with a bad past.
Ease Of Play is standard. Like every GTA game, there are standard missions, and then there are absolute cluster-cuss storms. Those missions in the last category will likely test a player's skills. Hand-Eye coordination, reflexes, and concentration. This is especially true in yoga, a new and surprisingly difficult minigame.
Violence. I'm not going to lie, GTA V is full of violence. There are shoot-outs with gangs and police members, there are intense fist-fights (Now and again with a man who is working out, only to be called out upon due to the possibility of his underwear belonging to Trevor), and there are random killing sprees by the player upon innocent bystanders. The cops are not lenient, and will arrest you for challenging them to a staring contest. The most violent scene is when you must interrogate a criminal for information, resulting in the use of a few torture methods. However, apart from that one torture mission, there aren't a lot of blood-baths. Blood flows realistically, meaning that a shot to the head does not result in a volcano of gore. More likely than not, there's a small, red hole where you hit them, and a puddle of blood. Nothing outrageous. And when you hit someone with a car, they will not explode in a shower of guts. They will sail over your hood and fall on the ground, dead. No excess blood.
Now, onto the touchy matter of sensual content. I will not lie, it is there. There are strip club mini-games, with topless nudity. There are prostitutes on the street corners, and there are multiple references to the act of sex. However, these are all 100% avoidable. Mission in the strip club? You can enter a cheat to skip it, or download a save file that starts at the next mission. Prostitute on the corner? You simply drive on and don't let them in your car. References to sex? Try going through middle/high school without hearing things, and tell me how that went. It's there, but avoidable. Still, I recommend knowing your child and their strength of will before letting them get GTA V.
Language. Same as above, go through middle/high school, you'll be exposed to the same level, if not moreso, of language as you would get in GTA V.
Now, as to drugs and alcohol, same as earlier. There, but avoidable. You can get drunk or high, but it's optional. There are two times where it's unavoidable. One instance was Michael was drugged by his son, in which he dreamed about chimpanzees, aliens, and his family's disappointment in him, which propelled him onward to his taking control of his life. The other time was purely for comedic affect. I mean, everyone Trevor shot was a clown, and they exploded in purple clouds. Who couldn't laugh at that?
As to privacy and safety, this site's main concern is GTA Online, Rockstar's multiplayer mode for the game, which could "expose them to mature topics of conversation." Seriously, if you let your kid get the main game, the Online mode is a walk in the park for them.
On top of the content, the game is beautiful. There are rolling hills, a deep-blue ocean, an amazing cityscape, and a mountain which you can get to the top of for a shot of the most beautiful sunset that gaming has to offer. You will not be disappointed by these scenes of nature.
All in all, there are positive messages and role-models, along with the same amount of violence and sensual content as you would get simply by living in our world. If your 14-15 year old is mature and strong-willed, than this game is 100% okay for them.
