Fortnite and Fifa are some of the most popular games in the world, with nearly 300 million players combined.
But there have been concerns about how these games might lead to addiction by encouraging gamers to play for long periods of time or buy in-game purchases.
Earlier this year, the World Heath Organization (WHO) officially listed 'gaming disorder' as an illness, and the Duke of Sussex said Fortnite was "created to addict, an addiction to keep you in front of a computer for as long as possible".
On Wednesday, the Digital, Culture, Media and Sport Committee - which is made up of Members of Parliament (MPs) from various parties - questioned people from Electronic Arts (EA) and Epic Games about immersive and addictive technologies.
The makers of popular battle royale game Fortnite have suggested that the Duke of Sussex was wrong to say the platform is addictive.
Canon Pence, a lawyer for Fortnite developers Epic Games, said the company was surprised by Prince Harry's view.
Mr Pence said that the suggestion that the company set out to gain short-term profit was a "real mischaracterisation".
The statements that were made, in our view, couldn't be further from the truth from our intentions and design philosophy.
When asked by committee chairman Damian Collins whether or not Mr Pence thought that the Duke had got it wrong or had a lack of understanding about the game, he responded: "I do."
Prince Harry made the comments in a meeting about young people's mental health in west London in April, in which he discussed negative impacts on the mental health of young people.
He said the platforms can be "addictive" and that they are all the more dangerous "because it's normalised and there are no restrictions to it".
EA was also asked by the committee about the issue and about how long users could spend playing games like Fifa.
The company's UK manager Shaun Campbell said that while the game was indeed designed to be "engaging and fun to play", he said EA wanted players to take a "healthy and balanced approach to playing games, just like anything else".
