cryengine is easy to make stuff look good in, the lighting is fantastic and the material rendering is pure awesome.
the pipeline for cryengine is not that great though, and certain things just aren't very well supported or developed at all. this is easy to see when using the sdk for mods, the animation and physics sysems leave a lot to be desired.
i think it's a great engine and would love to work with it again but overall i think it really lacks a lot of important features and the architecture surrounding it don't make it that easy to work with in a professional environment.
i think what makes crytek games look so good is the artists and programmers and animators and designers that make them. some of the most inspiring people have worked on their games and it shows.
then you go and look at some other people who have licensed the engine and it looks like shit.
