I used to work on a mod team on the CryTek forums for side projects and i agree.
It's honestly my opinion that after CE2 it just wasn't made to develop games. I'd begin to list off the amount of games that found the engine was more of a hassle for the little bit of extra eye candy but i can use CryT's Crysis 2 and 3. They're both basically super short tech demo's of the engine and neither of those games work properly. Geometry is LOL, the UI is buggy 99.9% of always, textures don't load, scripts go missing in the matrix. You'd think oh well that's just poorly put together games but nope. You can save a session on the Cry3, reopen it immediately after what you just tested and something will be broken.
I've always liked to just fool around and world design for fun (the easiest stuff) and of Unity, Unreal4 and Cry3... Cry3 has the highest potential to look pretty, hardest to work with.
