Do you like spending your spare time playing computer, video and online games?
The effect that your hobby has on you is the focus of a new government study.
It's been claimed that violent games can make kids behave badly.
Some research suggests that gaming can lead to kids skipping school and putting on weight.
But how does gaming affect YOU?
Do you feel that it's a bad influence, or do you just see it as a fun activity that wouldn't affect what you do?

"You CAN'T ban games. It's not just children that play games, my dad and older brothers play on them and I don't think they affect me or anyone I know."
Adam, 12, Southampton, England
"I disagree that it affects my mind. I play on 12, 16 and 18 games and I think they are really good and it makes me angry. I don't get nightmares."
Adrian, 10, Middlesbrough, England
"I think that some games should not be allowed because, if young children see, they will think it's ok to do things like that."
Lauren, 10, Middlesbrough, England
"Gaming can't affect you because I have played on violent games and nothing has happened to me."
Bethany, 10, Middlesbrough, England
"I always play shooting games and things like that and they don't affect me. People act violently because of the environment around them, not the things they do and play."
Sam, 13, Burton-upon-Trent, England
"I find it fine but my younger brother gets scared when he sees something violent when he plays."
Thomas, 12, Princes Risborough, England
"I have two violent computer games and they have affected me, but in a good way. Before I got them I could not control my anger, but now I have them I can control my anger. Sometimes they let your aggression come out so you are not aggressive."
Jacques, 8, London, England
"It doesn't affect me, I'm one of the best behaved in my class and go on games for hours!"
Kaleem, 10, Worcester, England
"My little bother played on a violent PS2 game which he had access to at his cousin's house. For about two weeks afterwards he was going on about dying and blood squirting out when he kills the people."
Bibi, 11, North Shields, England
"I mostly play on my PS2 and I only play at weekends. I do play some games which include violence but I play them for fun, or to let my anger out, and playing games doesn't affect me at all as I normally don't play for too long."
Shehzeena, 13, London, England
"I play on violent games and it doesn't make me want to go out and steal a car, shoot someone, or stab someone. Video games should not be blamed for the cause of violence! People play video games because they want an experience they won't get in reality! That's why we sometimes play games that are violent, full of action and partly realistic."
Thomas, 13, Kent, England
"I think games are good because in most of them you have to read difficult words. Also on the Nintendo Wii you get exercise. As long as you get a break after an hour there's no damage!"
George, 11, Fawley, England
"I think if you spend a little time on video games or on the computer it is OK, but if you stay on for loads and loads of time I think it could affect your brain."
Lil, 9, Ripon, UK
"I think that gaming can be both good and bad. It is down to advertising in my opinion. My little brother has seen 18 or 16-rated games and now he wants them even though they are far too violent and inappropriate for a boy of his age. If society is worried about certain games then they should make the certificate on them higher or just ban some types of games. Many children will try to rebel against certificates - I know a 13-year-old who has got into 15-rated movies and bought games etc. It shouldn't be that easy, but since violence can come from TV as well as video games, why are games getting the blame?"
Hezzi, 11, Scotland
"The only computer games I play are ones involving cute fluffy kittens!"
Charlotte, 9, Norwich, England
"If games are bad for children then there would be no games on CBBC website, and that would make it boring."
Martin, 12, Penryn, UK
"Kids who play games not designed for their age risk being exposed to violent content. It is up to the parents to police what games their children play. It shouldn't be the responsibility of games developers to phase out violence just because parents don't check the age limit for games before buying them for their kids."
Oncin, 11, Rickmansworth, England
"I think games are good because they teach you things like literacy. Also they help your imagination."
Aslak, 10, Waterloo, Belgium
"I don't think gaming itself is bad, but what I think should happen is that games that encourage violence should be banned. Also, gaming can have an effect on your eyes as well as your brain!"
Kasey, 12, London, England
"I have a number of games consoles and I am not affected by playing on them everyday. I still get good marks in school and I wouldn't say that I'm badly behaved. I really don't think that it's computer games that affect kids; it's more about where and how they live."
Emily, 13, Felixstowe, England
"I think some computer games are bad for you because they can become addictive, which makes people spend too much time on them and not enough time playing active games and sports."
Huw, 12, Oswestry, UK
"Do they stop kids from pretending to be warriors when playing outdoors? Not really, as long as it doesn't get too rough. So why is gaming any different? Do they really think kids are unable to tell the difference between virtual games and reality? I think this is just covering up core issues to do with upbringing and home life that need to be addressed."
Gemma, 12, Swindon, England
"I don't think they do make you more violent. I've been playing games since I was three, I like the violent games, but in real-life I hate violence. In fact my school tests show I'm very intelligent, and I get most of it from games I play, not ones intended for learning either. It can help you move your fingers faster, help with hand-eye co-ordination and more. With skills like that, you could become a designer, computer specialist and more."
Adam, 13, Rochester, England
"All the benefits games have given me are good. It's a good way to have fun with your mates and it can help you with hand-eye co-ordination, multi-tasking and reactions. The internet on the other hand has had mixed blessings. There's so many disgusting and repulsive things circling the internet that I've become de-sensitised."
Andrew, 13, Wirral, England
"We think children should try to avoid playing violent games. We are worried that violent games put pictures of fighting in your head which will make you want to fight later on."
Blue 1 Class, 7 and 8, Coventry, England
"This issue has only been brought up again because broadcasters need something to broadcast. It's obvious that sometimes violent computer games make children violent."
William, 12, Barnsley, England
"For me, computer games are helping me with my education as my mum and dad do not let me play unless I have done all my homework! So in that way it can be seen as a good thing."
Aisha, 12, Leeds, England
"Kids like playing video games, I don't see what's wrong. Give us a break!"
Aidan, 12, Swansea, Wales
"I play computer games and it has no affect on me. It's just when kids start playing and pretending to be a wrestler you have got to worry. Games affect your eyesight and I've played on my computer since I was six. I had an eye test a few months ago and my eyesight's perfect."
Hannah, 12, UK
"I love video games. I have every game console, even the PS3. I must have spent loads of my money on games. I'm not violent or fat and I don't skip school since my mum won't let me."
Sophie, 12, Northampton, England
"A game is just a game! People who think violent games make kids violent are probably violent people which is why they think like that!"
Lamin, 11, Birmingham, England
"My brother always plays wrestling games and he LOVES watching wrestling which can sometimes be uneasy. Even though he is my twin, sometimes he thinks he is a wrestler and does all sorts of moves on me and I wish he wouldn't be allowed to play on it. My mum and dad know and they have confiscated his game but he carries on watching wrestling and it is really painful!"
Marnie, 10, Wallasey, England
"If it's claimed that computer games affect kids' behaviour, the government also have to look at other types of entertainment like films or music. If anything, music would be a bigger cause as computer games and films have a rating system which clearly lets parents know what their children are playing or watching and music doesn't. It has a sign which states it has bad language in it, but it doesn't prevent you buying it. If kids are playing violent games which are rated above their age, then it's up to the parents to supervise them. "
Gordon, 11, Glasgow, Scotland
"Playing games may give you bad eyesight. You might have to wear glasses. THAT'S WHY I DO NOT PLAY COMPUTER GAMES!"
Sharaniya, 10, Kent, England
"Games don't hurt anyone. Blaming gaming is wrong and not the real problem. It's crime and poverty."
Damien, 12, UK
