Improbable is a new UK-based startup led by some extremely bright alum from Cambridge, and even if you haven't heard of it now, you likely will very soon. Here's their mission:
Improbable is developing an operating environment that makes building simulated worlds possible. Worlds which can be run in real time, simulating the behaviours and interactions of millions of entities. Spaces with their own rules and properties that a multitude of people can simultaneously change, explore and visualise in as many different ways as developers can imagine.
That's a bold statement, about as bold as anything Philip Rosedale has said about High Fidelity. But some very smart people are backing them, including venture capitalist Chris Dixon, who just led his firm to invest $20 million in Improbable:
Developers who use Improbable can write code as if it will run on only one machine (using whatever simulation software they prefer, including popular gaming/physics engines like Unity and Unreal), without having to think about parallelization. Improbable automatically distributes their code across hundreds or even thousands of machines, which then work together to create a seamlessly integrated, simulated world.
This actually sounds a lot like Philip's plan to deploy High Fidelity via distributed network, but leave that to one side. Point is $20 million is a lot of money, and Chris Dixon led his firm's investment in Oculus VR before Facebook bought it. And as compared to High Fidelity, Improbable has the lead on content creators so far. Take this endorsement by DayZ creator Dean Hall, who's now creating his game with Improbable:
