I am writing a research paper. Application developers on Unity, CryEngine 3, Unreal Engine, need your help, can you take the survey, please?

Question

Game development

Hey guys. I need your help. This post is for application developers on at least one of the three game engines.
I am writing a research paper comparing three game engines: Unity, CryEngine 3 and Unreal Engine (or the free version - UDK). Can you take a short survey in Google Forms? It will take you no more than 10 minutes.
I will duplicate what is written in the poll: I ask those who have not worked with any of the listed engines or have no experience with them to vote, please do not vote. And without cheating, please, because we need reliable data.
Thanks to everyone who responds, and thank you for your understanding!
Poll: goo.gl/forms/sLj3Kne7ix
Yes, by the way, if this topic is of interest to the people, I will publish the results of the study. [You can write to the mail, there is in the profile.]
PS The rating of CryEngine is especially welcome, now only 3 out of 47.
PPS While writing and preparing, I saw a lot of reviews and comparisons, but not a single one that would be detailed enough for me.
Plus, doing your own research is much more interesting.
Plus, I did not find mass polls.

Answer 1

The survey is more amateur than expert.
There are no such important points as: did you have to modify some part of the engine yourself (UI, network, AI), how long did it take to finalize system things, did you have to resort to crunches and emergency optimization (asm, calling and swotting on the brains of developers engine), how did the engine fit into the company’s infrastructure, did you have to hire any additional people, did you have to buy additional equipment (servers, etc.), integration of new employees (immediately started working or stupid 2 months in the documentation), art pipelines (difficulties , expectations, reality) if you decide to change the engine in the middle of the project (how much would it cost you and would you risk it).

Answer 2

Funny test. Filled in (unfortunately I am very little familiar with CE, so - Unity3D).
Only I'm wondering - a purely personal assessment (even without any comparisons ... "GUI convenience" - compared to what? For example, compared to Ogre3D, there is a solid five, with a plus - because the ogre does not have a GUI, as such. ..)
In any case, good luck with your research :)
