The player-vs-player, last-person-standing shooting game produced by Epic Games can be classed as an international success with at least 200 million players world wide in November 2018.

It's popularity has not gone unnoticed with plenty of debate questioning the impacts it may have on the younger people playing it.

SpoilerAlert games store owner Joseph O'Donnell, who sells the game's merchandise and has played it said he'd seen the game growing in popularity at gaming expo, PAX Melbourne 2018.

"People do primarily play online. It's a battle royale type game where 100 people are dropped onto an area and hunt each other," he said.

"The game genre originally started by realistic military simulator, however Fortnite has a more cartoon style which appeals to both younger audiences and older crowds.

"The last figures I saw was about three million con-current players so it's absolutely popular. I have video game merchandise in store and it sells, it's pretty popular."

Mr O'Donnell said have there have always been discussions about video games and their benefits for better short term cognition but no concrete evidence.

"There are studies which show games like this produce better short term cognition, short term problem solving but I wouldn't oversell it," he said.

"It's accepted these benefits are not greater than playing cricket or other sport every day."

Healthy Kids NSW, an initiative of the NSW Government, recommends children spend no more than two hours each day on the computer, small screen games or watching TV.

The website details the effects of too much screen time as worsening posture, deterioration of eyesight, wrist, thumb or elbow strain, sleeping problems and social skill deterioration.

MacKillop College acting principal Cath Eichmann said there were concerns about what impact video games had on a student's sleeping patterns.

"Our biggest concern is the impact it is having on students' sleep. Many students tell us they go to sleep well after midnight and even as late as 3am," she said.

"Obviously a lack of sleep impacts on the physical and emotional well-being as well as their ability to concentrate on their school work."

Ms Eichmann said MacKillop is holding healthy sleep presentations to students, staff and parents from a sleep expert in term two.

St Agnes' Parish Secondary Schools will also be doing the same including St Joseph's Regional College and Newman Senior Technical College.

Healthy Kids NSW encourages parents to work out a TV viewing schedule, limit time on the computer during the daytime and maintain a list of active things to do.

A survey based on the Fortnite community in 16 countries across the Americas and Europe in 2018, found 53 per cent of players were between 10 and 25 years old, according to marketing intelligence group Newzoo.

Another survey of 1000 American Fortnite players compiled by online financial marketplace, Lend Edu found about 35.12 per cent had missed school and 21.62 per cent had missed work to play the game.

NSW Department of Education spokesperson said they were not aware of any concerns about the video game, Fortnite.

"The Department is not aware of any concerns about the Fortnite game in public schools in Port Macquarie," they said.

"NSW public schools regularly provide general advice to students and parents about online safety."​
