Gaikai is a revolutionary new technology that lets you play any game online in your browser. In the age of the cloud, when all your documents, email, photos and videos are instantly reachable online, it seems archaic that you still need to install gigabytes of game files on an expensive PC with an even more expensive video card. And even then you can only play from that specific computer!
Gaikai takes a radical new approach – we host the games, we run them, we worry about hardware and software updates, and we stream them to you. Full resolution, full speed, stereo sound, low lag, no compromise. The only thing you need is a browser and an internet connection.
We call this Streaming Worlds, taking the full richness of modern computer games to anyone, anywhere, anytime.
