Unity has changed its terms so that devs now require a Pro license key, which Sony offers to creators but Microsoft doesn't.

Back in June, Unity announced that their cross-platform game development engine would support Microsoft’s Xbox One. Even better, the Xbox One Unity tools would be free! But there was a catch ...

Some individuals, however, lamented the requirement of picking up a Wii U dev kit for $7,000 in order to justify a free license for the Unity game engine, but it sure does beat the $500,000 price ...

Sony Computer Entertainment have partnered with Unity Technologies to offer Unity Pro for PlayStation 3, PlayStation 4 and PS Vita to licensed PlayStation developers at no cost.

The new Unity 5 Personal Edition doesn't cost a dime, and developers that make under $100,000 a year won't have to pay royalties, either.

Game engine maker Unity has launched a developer program to help its users build experiences to run on the forthcoming Apple Vision Pro.

Even so, it's nice to hear that Microsoft has struck a new deal with the engine-maker that means any Microsoft Studios-published Xbox 360 and Xbox One games will have access to Unity for free.
