1. Is Play Endorsement?
No, I don't think play is endorsement because its just a video game and let people play what they want to play. They said that its different in Call of Duty because you can be the good guy but in GTA V your always the bad guy. In  Call of Duty, your still killing people.
2. What do you get from playing?
If people like playing this game then they enjoy it so they get enjoyment out of the game. Its not like they are killing people in real life, its a video game! Let them play what they want to play. If you enjoy killing then you have something wrong with yourself. Its the game that they are playing, yeah it has killing, etc.. but still its just the enjoyment of the video game.
3. Who else is playing in your life?
No one that I know in my life right now is playing it. If I found out that they had it, I would like to play it to see how it works, and how it shouldn't bother people. It is a game mostly for teenagers, but if older people want to play it, let them have there opinion. Everyone has an opinion.
4.Do you know when to quit?
Its a little different when your skipping out on important things in your life for GTA V. You shouldn't miss anything just because of a video game. Take time for other things in your life, and not just for a video game. Don't get caught up in the game for hours and hours and not even realize it. That's when it gets bad. Play the game because you enjoy it, but don't get to caught up in it too long.
