We know that Fortnite is a pretty big deal right now, sweeping the globe with its addictive shooter survival format. According to Business Insider, the game is so popular that after just six months, it was briefly the most-watched game on streaming platform Twitch - and it's still up there.
But one dad got a bit of a bum deal when he found out his son had managed to spend almost £700 of his money on the game.
Steven Harrison, 37, said that 12-year-old son Tyler managed to complete 81 transactions in three days before he found out what had happened.
In total, Tyler managed to rack up £691 ($918) in bills on the game... which is quite a lot, especially given that the game itself is free.
Despite the fact that Tyler's gaming was leading to irregular activity on his bank account, Steven said the bank couldn't have done anything about it because he was deemed to have authorised the payments.
Steven told the Birmingham Mail that he believes NatWest should have flagged up the activity earlier, admitting that he'd forgotten he had left out his bank details after letting his son buy a birthday present.
He said: "I just want to warn other parents to be careful."
A NatWest spokesperson said: "We sympathise but we are not able to refund the disputed transactions because the card use was contrary to our terms and conditions."
Steven is far from the only parent who's grown concerned with his child's Fortnite addiction.
One mum appeared on This Morning to warn others about the dangers of the game, after she claimed it had changed her ten-year-old son.
She explained that Fortnite had made him start ignoring family time in favour of being sat in front of his XBox, with the game's constant energy making him find normal life boring in comparison.
The Daily Mail also reports that staff at Greenways Primary School in Stockton Brook, Stoke-on-Trent, wrote a letter to parents last month, warning them about the game - following complaints that some students were becoming 'distracted' and were spending too much time talking about the game.
In an email to parents, headteacher Jemma Garside wrote: "A new game has become popular with the children in school - Fortnite, age-rating 12.
"Unfortunately, discussions around this game are being brought into school and into the classroom which is distracting children from their learning.
"Can you please speak to your child about this so that learning time is not lost dealing with issues linked to this game."
