CryENGINE®3 is the first PC, Playstation®3, and Xbox 360™ all-in-one game development solution that is Next-Gen ready with scalable computation and graphics technologies. Using the CryENGINE®3, you can start the development of your next generation games today. CryENGINE®3 is the only game engine that provides multi-award winning graphics, state-of-the art lighting, physics and AI, out of the box. The famous CryENGINE®3 Sandbox™ editor is a production proven, third-generation real-time tool suite designed and built by AAA developers. CryENGINE®’s powerful real-time renderer is now even better! DirectX 11 (DX11) support significantly enhances the capabilities of the renderer within CryENGINE®3, allowing for some of the best visuals ever seen.
I chose 10/10 because i really like the overall look and feel. Next to the awesome graphics it comes with an easy to handle, but powerful editor for maps and flowgraph. I really aprechiate for the bundled engine-code, so that developing is not a hassle with derping aroun in LUA or the Flowgraph, but can directly be integrated into the Engine itself.
And those facts have also made my choice to develop my game with the CryEngine3, because Unreal IS powerful, BUT the relation to the useness-level is quite diffrent. While the CryEngine is easy to handle, but powerful, the Unrealengine is powerful the same way, but much harder to handle.
Some may call this lazyness, not to use the harder engine, but i call it effectiveness. More that can be done in the same time.
All above is MY PERSONAL OPINION!
A great new addition to the industry. Unity and others better watch out!! Being first out the door doesn't guarantee dominance!! These guys have got a workable and clearly defined plan to hold the middleware audience enthralled!!
