AGF Pro, is Axis Game Factory Pro, a completely different developer
It's not just one tool, it's a group of tools linked together to make a full package game creator, for example one of the packages is a tool that allows you to take multiple meshes and weld them together to make a single entity.
It can be used as a game creator in itself, and is quite good, but what it's best at is creating scenes, then exporting them to Unity packages, which you can then refine in Unity.
It's Unity based, technically it's Unity 4 with a different UI and some custom tools, so you can create packages in Unity and import them into AGF and vice versa.
I've had it in my steam collection for ages but only ever messed around with it, it's control system is very much like blender, lots of hot keys, and lots of ctrl, alt, shift work with the mouse.
