facing unity editor without any 3d knowledge can be a bit frustrating, and you have to deal with and organize a lot of asset and code packages


This is not to say , it's the best , but ...
In that point you can find the basic Third person tutorial that explains step by step to make the game stage by stage :
- adding the character
- adding the camera and adjust it
- adding a particle effect and adjust parameters
etc ...
It's really complete and also includes scripting code snippets and some ennemy and basic AI code.

For adding textures models, you have a complete browser panel and where you have created the project where you will be able to import pre defined stuff or simply create new sub categories and add all your stuff.

Well, that you that make a game, not totally the engine.
But yes, good features , easy to apply, more fluid workflow will bring more pleasure to make the game.
A good 3D editor not only the engine counts on people happiness i find , specially non programmers.

With 3DGS you can make lot of little games , or worlds zones loading levels or arcade etc ...
Not all 3DGS users have solide some game idea, and 3D graphic skills ... a lot are more programmers.
Let's hope some future version will attract more skilled team or people on the 3D graphics models and textures side ?

This also popular games that make 3D engines popular also
