Which engine to choose for developing online games?

Question

PHP

We develop online games based on C2. We thought about switching to a more productive engine that will allow us to make 3d / 2d games with the ability to play on the web and mobile markets.
What engine would you recommend and why?
We are considering several options, many of them allow you to make toys for mobile devices, but do not allow you to use the web and desktop applications. Share your experience.
Here is our selection:
UnrealEngine, CryEngine, Construct2, Unity3d, build box, CreateJS

Answer 2

blend4web, because:
Smartphones - https://habrahabr.ru/post/266939/
Social networks - https://www.blend4web.com/ru/article/146/
3D browsers
- www.petigor.com/apps/petigors_tale/ petigors_tale.h...
2D - https://www.blend4web.com/ru/forums/topic/1992/ Pros
:
Development is in Russia (documentation and support both in Russian and in English)
programmers are not in the know, the artist himself).
And in general, it allows you to make an adequate pipeline out of the box.
Well, what is written on the site)
Cons
In general, not a game engine (there are no some features of the scene designer)
There is no network engine out of the box (only implementation from one programmer from the community https://www.blend4web.com/en/forums/topic/492/?page=1)

Answer 3

Unreal Engine 4:
1) Huge community
2) A bunch of offs. assets.
3) Support vr and mob. devices.
4) Graphics that Unity doesn't even smell
of 5) Optimization
Example: I myself worked with both Unity and Anrial. Unity started to lag on a level with a small terrain and 100 objects. Anrial took out 20x30 sq. kilometers + 500K trees and more than 1M grass sprites and more than 300 objects with different textures + light + dynamic shadows. It took less than an hour to make the change of day and night with the movement of the sun. Simple, convenient.

Answer 4

Unity3d is C# and has a huge community. The new versions have good graphics, easy development, a lot of plug-ins.
