It was Cryengine you were using before, right? How difficult was using it compared to the Unreal Engine?
Entirely correct, we were indeed using the Cryengine.
Honestly for a level designer, Cryengine is the best engine I could ever ask for. The solid tools are fantastic and allow you to pretty much model within the engine itself.
I loved everything about the tools in the Cryengine. The problem is, everything else about it. The animation tools, the flowgraph system, the coding and etc.
I honestly want to use the Cryengine, and we got quite a bit of work done in that engine, but it's selfish for us to want to stay on that engine in a lot of ways, because it screws over everyone else besides the level designers.
Unreal Engine 4 is better for everything on the planet, except for it's BSP tools pretty much; the geometry editing tools aren't as flexible as Cryengines edit tool.
I think the only real delay in this game was the fact that the first engine I ever used was the Cryengine, and I got really good with that, and switching engines caused a lot of trouble because I was deprived of a lot of tools I had grown used to. In fact I recreated the Mall level from Timesplitters 1 entirely in Cryengine 3, without any imports of any kind; something that would be impossible with Unreal Engine 4 practically.
