It was all about games for Sony and Nintendo, while Microsoft unveiled its new Xbox One X gaming console at the Electronic Entertainment Expo (E3) 2017, held last week at the Los Angeles Convention Center.

The annual event is the "mecca" of PC and video gaming where game industry professionals, such as publishers, developers and distributors, gathered over three days to look at the latest games and gaming wares.

Nintendo did its usual webcast press conference before E3 and announced a new platform game in Super Mario Odyssey, as well as a Pokemon role-playing game for its Switch console.

Sony's E3 media showcase consisted of video trailer after video trailer of PS4-exclusive games such as God Of War and Marvel's Spider-Man.

"That is the clear intention that we have," said Mr Shuhei Yoshida, president of Sony Interactive Entertainment (SIE) worldwide studio.

He felt that, instead of having developers on the media showcase talk about games, it was better to just show the best games for the PS4.

Last year, SIE was focused on the launch of new gaming hardware like the PS4 Pro and PS VR, said Mr Yoshida. With those out of the way, SIE can finally concentrate on rolling out PS4-exclusive games.

"We can focus more on the games because that is what people are looking forward to," he said.

On the other hand, Microsoft used E3 to show off its new console, the Xbox One X. New Xbox One exclusive titles, such as Forza Motorsport 7 and Crackdown 3, were also showcased.

Xbox One X is the most powerful gaming console built, according to Microsoft. Available later this year, it features an eight-core custom AMD processor and a six-teraflops graphics processing unit for true and smooth 4K video gameplay.

"We are really proud of what we are delivering with such unheard-of processing power," said Mr Zeph Stuart, head of Xbox and Windows gaming, Microsoft Asia.

The One X will be priced at $699 in Singapore, which is $100 more expensive than its PlayStation 4 Pro counterpart.

"When we showed the specifications last year, people were speculating that it might cost twice as much (as the announced price)," said Mr Stuart.

He emphasised that the One X is a premium device for dedicated fans and provides great value for its performance.

Thankfully for Microsoft, Sony will not be reducing the price of its latest PS4 Pro gaming console.

"People are very happy with the PS4 Pro, so we do not have any plans to change the pricing," said Mr Yoshida.
