Ready At Dawn Have Created Their Own Commercial Cross Platform Engine.

They also handled the Wii port of Okami. Now they've made their own engine for the Playstation 3, PSP and XBOX 360. It's craftily titled: Ready At Dawn Engine.

The engine is said to offer a one-stop shop for cross-platform game development merging its "proprietary code-base with the top providers of 3D content editing, audio, user interface and asset management systems." We've no idea what that means but chances are if you take any interest in this, you'll understand. Which is the point where we direct you here, oh wannabe game developer.
