Well this engine is not for newbbies or 3D total game beginners even if they could achieve something.
It uses some similar C++ that compiles ont top of Visual Studio.

Esenthel 2

Here are key features of Esenthel Editor 2.0:

Fully collaborative game development:
Automatic, real-time and in-background game resource and world synchronization between all game developers


Greatly simplified resource importing/processing:
Most resources are imported in background thread to avoid pauses during importing

Easier setting of material textures
Easier setting of mesh LOD's

Easier resource management:
All resources are visible in Project View as nodes
Resources can be re-arranged at will (renamed, moved to different folders, etc) without the need of making any extra changes (both in resources or game code)
You can switch between projects and create new ones directly in the Editor without restarting it
Easier game packaging:
All resources can be automatically packaged for you when publishing the game

Better interface:
Interface is focused on functionalities that are used most often
More focus on mouse usage and drag and drop functionality

----------------

Following functionalities are still in progress but will be available in final release:
Particle Editor
Icon Maker
Environmemt Options
Ocean
Mac and iOS support (currently only Windows and Android)
Undo support (it's unavailable and it's unknown when it will be)
Some model editor options (physical cloth editing, configuring mesh parts for visibility)
World mini-map generation

Note the license have changed , it's no more per title, but per site for V2 !
So 100$ for full engine version and unlimited projects and so advanced engine ...


-------------

The APIs used are these :
Esenthel Engine is based on: Nvidia PhysX - PhysX EULA, Microsoft DirectX SDK, Bullet, Recast/Detour, Vorbis, Theora, Zlib, Snappy, LibPng, LibJpeg, Jimenez's MLAA (all of them are free to use, only Nvidia PhysX imposes some requirements, please read them carefully)

What does it means for Nvidia ? We use it with 3DGS freely, i don't think they impact the game you make with them ?

------------
You'll purchase Esenthel Engine 2.0 for reduced price of 99$ (once engine will be finished its price will rise to 150-200$)
It remains cheap, but purchasing now i think is a good option
------------

BUT ONCE AGAIN , IF YOU CAN'T ACHIEVE TO MAKE A COMPLETE GAME OR TO CAN'T PRODUCE GOOD 3D ART AND STUFF, the ENGINE WON'T MAKE A BEAUTIFULL GAME OR AMAZING 3D ART FOR YOU AT YOUR PLACE
