People can't seem to get enough of Blizzard's latest title and first real venture into the FPS genre, Overwatch. Since its release two weeks ago, the critically acclaimed hero-based shooter has garnered millions of fans from across the globe, including the always-busy Tesla and SpaceX CEO Elon Musk.

In a tweet on Sunday 5 June, the Silicon Valley billionaire and notorious workaholic said he "highly recommends" the game, which involves battling AI-powered robots, if you like "ultrafast team FPS action". He also mentioned that he plays on a "PC, of course".

Overwatch responded to Musk's glowing recommendation for the game with their own humorous tweet referencing one of the game's popular characters, genetically-engineered gorilla and scientist Winston.

Blizzard's latest title has skyrocketed in popularity since its launch on 24 May, featuring a colourful roster of heroes, each of which sport his or her unique abilities and rich backstories. More than seven million players have logged 19 million hours in the popular game across PS4, Xbox One and PC since its launch. The game's widely popular open beta also drew 9.7 million participants across all three platforms, shattering Blizzard's internal records as the company's biggest beta ever for a Blizzard game.

Musk's tweet also comes on the heels of his recent comment that we all could be living in some advanced civilisation's virtual reality video game.

"The strongest argument for us probably being in a simulation is that 40 years ago we had Pong, two rectangles and a dot," Musk said in an interview with Recode on 1 June. "That was what games were. Now, 40 years later, we have photorealistic 3D simulations with millions of people playing simultaneously and it's getting better every year, and soon we'll have virtual reality. If you assume any rate of improvement at all, then the games will become indistinguishable from reality."
