I come from UE4 community , Its a great and powerful engine , very easy to learn and use and you could build nearly any type of game with it quite easily. Its main strong points are complete set of mature tools , a very strong architecture and large community support.
Last year Cryengine went free in the form of lumberyard, later it itself became free to use releasing as cryengine 5.
So I decided to take a peek into both, the latest I see of lumberyard is its going the same route as Unreal engine in its architecture (components,reflection,events etc etc) and improving tools and usability overall (might end up as UE4 clone with lua and forward renderer in a few years :P )
While I don't know much about cryengine 5 but it seems to be going more towards graphical enhancement route rather than improving usability and docs.
I wish to know about things that community thinks is different in CE5/Lumberyard that is something a UE4 user would desire but cannot get in UE4. Something positive that is exclusive to CE and has no proper alternative on UE4.
