Worried about computer gaming addiction, one game company is considering giving less bonus points the longer a player plays the game.

Mr Trond Aas who heads computer game developer and publisher Funcom said his company was considering doing this as a "conscious approach" to battle gaming addiction.

But ultimately, it is parents who should enforce rules when handling their children's gaming habits, said Mr Zareh Nalbandian, founder of computer animation company Animal Logic.

Mr Nalbandian said: "My children understand that from Mondays to Thursdays,there are no computer games. It is something they grew up with and they don't question it."

Both men were in Singapore last month as panelists on CNN's Future Summit:Virtual Worlds programme.

A joint project with the Singapore Tourism Board, the programme will be aired from June 16.

In an interview with Digital Life, they said that computer games are good entertainment and not addictive.

Mr Aas' argument: "People who say gaming is addictive and bad are wrong.

"Now people have stopped watching television and spend time online. Now, it is five hours on television and the rest online or gaming. What's addictive to some is entertainment to others."More important than addiction is violence,he stressed.

"If you're a responsible parent, you won't allow your kids watch age 18 movies when they are only 12 years old."

Mr Aas' company Funcom developed the well known Anarchy Online action game.

Started in 1993, the company now employs about 250 people in Norway and another 30 computer graphics professionals in Beijing.

The movie Happy Feet won Mr Nalbandian an Oscar for the producing the best animated movie.

His company, Animal Logic developed the digital effects which had the penguins dancing and tapping their feet.
