Our take
While online gaming is no longer a revolutionary concept, Roblox has established itself as a leader in the industry by creating a gaming toolbox that encourages quality game creation, which it pays developers for.
In addition to standard games, the platform offers virtual worlds and other experiences to explore and interact with. Its platform provides an online ecosystem for millions to create, socialize, chat, and explore immersive experiences with friends. In fact, in the US its used by two-thirds of children aged 9 to 12.
The experiences on the platform are made by Roblox's over three million creators, and are available on a range of devices from PC to Xbox to Oculus, and more. The company has grown at an impressive rate, and has been keen to adopt new developments in the tech world, for example with its real-time AI translation for players to interact outside their native tongue.
