Back in July of '09, Microsoft made its Kodu game creation toolset available on Xbox Live for 400 MS Points. Well, now it's being made available to PC owners via Connect.Says
Ars, "Since its release, Kodu has been downloaded more than 200,000 times and is used in more than 60 educational institutions across the globe, according to Microsoft."
The PC version has some upgrades on the Xbox 360 version such as "deep enhancements to the 'move' verb (for example, a character can follow a path while watching another object), nested logic allows more powerful combinations of sensors and actions, streamlined terrain editing tools, and the ability for characters to respond to mouse and keyboard events. Since this is a beta (technical preview) though, there are some known issues: the in-game help still references the game controller in some places, some low-end PCs may have a problem running Kodu (try using lower-quality graphics settings), most of the built-in content is designed for controller play, and the new export function isn't very clear (the exported .kodu file is placed in your documents folder under SavedGames/Boku/Player1/Exports)."
