Multiple grain of control over any kind of engine setting and various kind of Lod systems. Settings can be grouped and applied in batch.
Pro Is the first engine to feature SpeedTree 8
Pro Perforce versioning system pre-integrated with the tools
Perforce also comes with a free version for a limited number of team members.
Pro Cutting edge character shaders
Has skin shaders with subsurface scattering and weighted wrinkle maps, eye shaders with refraction parallax, hair with anysotropic specular reflections, etc.

Pro Implements the state of the art for Temporal Antialiasing from NVIDIA Research
Special iteration of Temporal AA to battle the ghosting issue omnipresent in engines using other Temporal AA techniques.
Pro New Fbx Importer adds support for every software exporting in fbx
It now works for both static models and animations and support advanced setups(es lods and physics).
Pro Full HDR renderer path with output support for HDR tv standards
Updated renderer pipeline to leverage the full spectrum of precision, luminosity and image processing features of the latest HDR tv.
Pro Cinematic multitrack tool with full featured animation editing
Animation Spline editor supporting huge range of keyframing and tangent editing tools.
Pro Advanced in-game UI with 2D and 3D placing
The UI uses the entity component system so it's fully modular and easily expandable. The UI is easily skinnable and supports border scaling images (scale 9). Powerful layouting system supporting multiple screen resolutions. Being based on the entity system every property can be fully animated.
It is elegantly managed in a separate entity context so it doesn't get messed up with other kind of entities and their components like in other engines, but it's fully decoupled communicating with entities in other context on specific event buses.
Pro Full source code repository with updated development branch now on GitHub
See here.
Pro A proven engine for mobile development
25% of iPhone games are made using Cocos2d-x.
This means you will not be alone in development, and will have access to a large community. You'll know you are developing for an engine that works.
Pro Good documentation
Documentation includes a programming guide, API reference, video tutorials and massive reference test code project showing all functions and giving working code to the user.
Pro Supports 3D models with skeleton animation
A new feature since Cocos2d-x v3.1 is support for 3D models (in your 2D game), not only this but support for skeleton animations is included too! This awesome feature allows for impressive characters in your game along with easier, more fluid and realistic animations.
Pro Great script language support
It supports Lua and Javascript with full feature support.
Especially with Cocos2d-JS you can develop games cross web and native, and the native solution have great performance with JS Bindings, much better than hybrid solution.
Pro Highly active community for questions and support
Cocos2d-x forums are active.
Pro OpenGL hardware acceleration
Pro Future-proof
Cocos2d-x is not only open source but also supported by Chukong Technologies of China and USA.
Regularly updated and adding support for the latest technologies. 2014 has already seen the release of Version 3, a new Cocos Studio development toolkit (optional) and support for new technologies like skeleton animation systems Spine and Adobe DragonBone.
Pro Greater performance than high level APIs
Cocos2d-x is C++ based engine and it has CPU advantages for most platforms because of that. It uses polygonal mesh methods for sprite rendering for using GPU advantages. (You also use quad methods for benefit CPU).
Pro No external dependencies
Because it is based on Pyglet.
Pro One code for all platforms
On top of supporting pretty much all existing platforms (except consoles), Cocos Creator (Cocos's IDE) allows you to write 1 code that runs on Android, iOS, Windows, MacOS and HTML5 (not Linux though).
Pro Easy integration of 3rd party plugins
Through the use of SDKBox you can easily integrate 3rd party SDKs and plugins for each version of Cocos2D (Lua, C++ or JavaScript), you just choose the SDKs to integrate and SDKBox will do the rest.
For example, if you want to add a rating plugin, you use sdkbox::PluginReview::init();
and if you want to add the Vundle Ad Network SDK, you use the one packaged in SDKBox SDKBOX sdkbox::PluginVungle::init();
.
Pro Allows for easy debugging
It has a built-in Python interpreter that allows for easy debugging.
Pro Very good IDE
Cocos Creator (Cocos' IDE) comes with scene editing, UI editor, animations & particle editors and whatnot. It's also easy to use and pretty intuitive if you read the official documentation & tutorials. Way way better than the old CocoStudio.
Pro Great video tutorials
Hundreds of video tutorials available.
Cons
Con Some Legacy systems are still incompatible or not fit well with the new entity component system
At first it is common to try a feature and then understand that it is meant to work with the legacy system and not with the newest one.
Legacy systems get replaced or updated to work well with the new entity component system in every new version, but there is still some work to do.
One example for all Flow Graph visual scripting is meant for the legacy entity and Script Canvas is the visual scripting conterpart for the new entity system, but it is still not available at the moment.
Con No source code repository with updated development branch (requests for Github support currently pending)
You need to wait up to 30 or 60 days for fixes as they are shipped with the next official release.
There is no comfortable way to submit fixes and changes to the engine as the forum is the only tool for sharing code.
Con CryEngine with AWS plugins
Con Poor support and non-existent community
Up until 2013, this was one of the best engines around. However, since then it was bought by a Chinese company and began stagnating - it's virtually in a slow death. Most developers abandoned Cocos in favor of more modern solutions leaving the community weak and the forums with little or no traffic. Although the Cocos2d-x Forum seems to have a decent community going.
Con No Graphics user interface
Con Modest functionality
Almost all free alternatives are more convenient, faster, and more functional.
