When comparing Unity vs Esenthel, the Slant community recommends Unity for most people. In the question“What are the best 3D game engines?” Unity is ranked 3rd while Esenthel is ranked 9th. The most important reason people chose Unity is:
Unity3D provides an exhaustive documentation where everything is given a full description supplied by a number of examples as well as video and text tutorials and live training sessions to understand the ins and outs of the engine. In addition there's an ever-growing community that can offer advice to help resolve any situations that may arise. Along with the official Unity resources, there are [many high quality](http://www.slant.co/topics/346/~beginner-resources-to-learn-unity) (and often free) third party tutorials available.

Pro Easy learning curve
The way the editor is structured, by setting scripts on objects, and the use of a high-level language, C#, makes it easy to learn.
Pro Lots of assets can be found in the Asset Store
For those developers who can't afford an artist, or aren't skilled enough to create their own art, Unity features an Asset Store full of a wide variety of free and paid assets that can be easily added to a game. The Asset Store has more than just music and art. It also has code and modules that can be added to games including unique lighting or GUI systems. It also has powerful asset management and attribute inspection.
Pro Allows for rapid prototyping
Unity's modular system and usability allows for quickly developing a prototype of an idea. It has features like drag & drop editing, shaders, animation and other systems already in place to allow diving right into developing a game.
Pro Very popular
Unity is a proven game engine. It is used by a wide range of developers - from small indies to triple-A companies such as Microsoft, Paradox, Square Enix and Sega.
Pro Can be used for free
As long as the development company makes $100k or less, it can use the free version of Unity to release games.
Pro Great editor
The editor GUI is very powerful and intuitive. It allows pausing gameplay and manipulating the scene at any time as well as progress gameplay frame by frame. It also has powerful asset management and attribute inspection.
Pro Works with 3rd party IDEs
You can use any C# IDE for it, but the ones I tested which have Unity integration are:
- Microsoft Visual Studio
- MonoDevelop (comes with Unity)
- Visual Studio Code (much faster than VS, but a bit harder to set up for Unity development)
Pro Over 20 platforms
Unity offers over 20 platforms for publishing including mobile, console, web, VR, and more.
Pro Has a great animation system
Unity provides a great state machine animation system called Mechanim allowing to separate animation from the model and assign the same animoations to different models.
Not tailored for specific types of games (like Unreal...), so it won't get in your way if you want to make something unique.
Pro Very optimized
Unity runs very smoothly even on systems that are considered "weak" by today's standards.
Pro Powerful standard shaders
The built in standard shader in Unity 5 is incredibly optimized and supports PBS/PBR.
Pro OUYA support
Pro Can create custom forms and tools
Pro Flexibility is provided by a strong component programming model
Pro Has awesome plugins
Pro Free for mobile development
Unity allows free mobile development. There are some limitations.
Pro Quicker development by using the integrated code editor
Esenthel has a built-in code editor which drastically simplifies the programming process.
Programming with Esenthel is based on C++, however, when using the code editor there's no need to make separate .cpp or .h files. Code can be written once and the editor will be separating definitions and declarations automatically in the background allowing for quicker development.
Pro Can be easily extended
Built in pure C++ so it is easy to use and extend however needed.
Pro Engine issues are resolved quickly
The author is very device minded and able to handle any problem quickly and effectively and he has a good track record of listening to requests.
Pro Incredibly stable
The engine is rock solid and stable which, considering its extensive feature set, is a huge plus for game developers
Pro Helpful and responsive forum
Pro Constant development and progress
New features or update to features are provided monthly.
Pro Can import a wide variety of formats
- 3D - FBX, DAE, OBJ, 3DS, B3D, MS3D, BVH, ASE, PSK/PSA
- 2D - BMP, PNG, JPG, TGA, DDS, TIF, WEBP, PSD, ICO
- Videos - VP9, Theora
- Sounds - OGG, WAV, MP3 (once decoding patents expire)
Pro Available on Steam
Pro Can be used for collaborative development
Esenthel comes with tools allowing for multiple developers to work on one project at the same time in collaborative mode. Every change made is instantly visible by other team members.
Pro Attractive licensing
Free to try, with license as cheap as 9.50$/month (with yearly subscription), 11.40$/month (monthly subscription) or full source code license 228$/year.
Pro Access to full source code
Having easy access to the full source makes it possible for any skilled developer to add features that a project requires.
Pro Good support for Android and iOS
Android and iOS support is pretty stable and easy to develop on. It's possible to, for example, develop the entire game on Windows or Mac and then easily compile for Android and iOS.
Pro Rock solid
Pro Supports modern graphics and sound APIs
- Graphics - DirectX 9/10/11, OpenGL, OpenGL ES, WebGL
- Sound - DirectSound, OpenAL, OpenSL
Pro Oculus Rift native support
Oculus Rift API integrated into the engine platform.
Pro Supports multiple compression libraries
LZMA, LZHAM, LZ4, ZLIB, Snappy, RLE
Pro Supports in-app purchases
IAP support for both mobile and desktop devices.
Con Very bad terrain
Native terrain creates a lot of draw calls which is bad for performance.
Con Hard to maintain projects due to vendor lock
Unity3D is proprietary, closed source game engine. Unity asks money for features like basic version control support, etc. It is impossible to migrate a game from Unity3D in case performance does not satisfy growing requirements of a project.
Con Garbage collection can't be turned off
Given the use of C#, the memory control is out of the developers control, this can be good, but not controlling memory means that the garbage collector can trigger at any time and ruin performance.
Con Weak memory management
.Net libraries are slowing it down, memory safety is compromised, classes have to be implemented to manage objects in memory, like object pooling.
Con Very self-centered engine
Unity3D uses very unique approach for doing things. Most of the knowledge acquired while using it, would be completely non transferable to other engines. Advanced Unity3D programming is really dealing with Unity3D bugs, and finding loopholes around engine issues - nothing to do with graphics, etc. Skills which would be valuable with other engines.
Con Bad batching support
Draw Call Batching is done automatically and does not include Skinned Renderers (eg. characters). Also for dynamic batching, meshes need to have less than 900 vertices.
Con Encourages bad coding practices
A lot of Unity code feels like a hacked blur of arguable coding practices. C# and .Net usage in Unity is questionable. A lot of the API is done in "C Style" (public static methods, available at all times), encouraging the use of public fields for everything, a lot of questionable implicit casting. The list goes on.
Con Adds too many features without fixing earlier issues, rapidly increasing number of bugs that will never get fixed
Unity continues to add many new features without fixing earlier issues. Unity is either understaffed, overambitious, or both, resulting in a continual increase of problems and degraded experience across a number of platforms. Many bugs are reported daily and never get addressed, and there are many bugs from previous versions that are never looked at or fixed.
Con Increasing number of bugs
With each new version things may stop working ,for example with Android, some bugs are never getting fixed, like the freeze bug with adb.
Con Mobile builds (Android, iOS) take about 18MB at least
Even a Blank Project, Needs 18MB for the APK file (on Android).
Con Moderators on forums are sometimes arrogant
Con Dark UI theme not available in the free version
Dark theme, which is a must for prolonged work without eye strain, is only available with one of the paid monthly plans.
Con Asset bundles can be cumbersome
Asset bundles are a way to load external resources that are not packed with the game or application and offered as a separate, optional package. However, they may not be compatible between versions or even platforms (you have to create them separately).
Asset bundles need to be loaded and unloaded, avoid concurrent loads from web or cache or a naming collision can happen. You can find workarounds with static objects (load
obj files and textures by code), but for animated game objects you are pretty much stuck with this.
Con Price is very high
Cost is based on Revenue:
less than $100K = Free
between $100K and 200K = $35 a month per seat
greater thank 200K = $125 a month per seat
Con Docs have inconsistent choice of scripting languages
Con New il2cpp script backend is show stopper to some iOS projects
Il2cpp script backend is required to build arm64 app, but it's still very buggy and not production ready.
Con Comparatively high learning curve is putting it nicely. Expect to spend days upon days researching basic functionality.
Although C#, JS, and Boo have documentation available online, it can still be difficult to understand the library and Unity's component based system.
Con Bad input
Con Bad model importing
Con Bad raycasts
Con Slow roadmap implementation
Bugs are fixed promptly, but the developer maintains a growing 'roadmap' of features with no indication to users of time frame and priority of feature implementation.
Con One-man developer
Although the complete engine is maintained by a single, highly-skilled individual, he can be limited to what he is able to see or perceive, and sometimes he doesn't recognize broken or incomplete features until he sees it firsthand and sometimes doesn't recognize valid reports from his users. But when he does recognize the gap in the engine's feature-set, he is quick to make adjustments and updates.
Con Lack of in-depth tutorials
There are plenty of beginner coding tutorials which serve as a basic introduction for a new user to get up to speed, but once having passed that stage there is a real lack of free more advanced tutorials/examples/code snippets demonstrating the finer details of the vast and varied API functions.
Con Lack of editing tools
Con Web support practically non-existing
