Daz3D are giving away pro versions of Bryce, Daz and Hexagon.
Bryce is a landscape engine, for creating and rendering landscapes. It's been around forever and can be pretty stunning at times. Since it's the PRO version, it has COLLADA support, which means you can easily integrate it with your existing workflow ( Blender, Maya, Max, Softimage, UDK and Unity all support COLLADA ).
Hexagon is a 3D modelling app. It's been around for a while, and I think it might be kinda meh over all, but for free I am willing to give it a shot! Use it for creating 3D modelling ( only, no rendering or animation ), somewhat like Wings 3D.
Daz I don't really get, I need to try it first. At first glance it appears to be Poser, which is a rendering and animation package. Again this one supports COLLADA, so could be slotted into an existing workflow.
So, if you are a game developer on a budget, this is certainly worth checking out. It is time limited ( this month I think? ). All you have to do is "buy" the 3 items at 0$, and you get issued serial numbers, so you can download them later. There is no *gotcha* that I can tell so far, although you do need to register using a valid email address.
My guess is, they are trying to sell content packs, more like turbo squid.
