CopperCube vs HeroEngine

Includes easy to use 3D editor for quickly clicking together 3D games.

Can create 3D games as real WebGL apps, running inside websites. Doesn't use a cross compiler, so WebGL apps are small and download quickly.

CopperCube includes a terrain editor. Terrain can be drawn with height painting tools directly in the editor, textures can be painted quickly with automatic texture blending into the terrain. There are also tools for placing grass and bushes, and for distributing meshes automatically over the terrain.

It was also written by the founder of irrlicht, although it is not open source.

CopperCube is available on Steam It was Greenlit.

You can quickly develop an experimental working model of the product (prototype), because the engine gives you access to a lot of prefabs, plugins and settings. And, you can use the visual programming to speed up the process, even if later you have to write code in order to improve the final product.

Supports both DK2 and DK1.

Backend completely handled by the team at Hero.

No need for Perforce, Github or any other versioning software. It is built in. Check, Compare, Merge, revert, etc.

Developers of the engine and game developers are active on the Forums and Skype for private messaging.

Able to create many types of games and scales all the way from a single area up to a full-blown MMO.

Designed for the needs of a MMO. HSL is also relatively easy to learn as scripting languages go. It was geared towards beginners, not time hardened programmers, and as such, its easier for a novice to pick it up sometimes, than a c++ programmer. That, and it was intended to be "readable" more like English.

Skype channel and forums questions answered by developers of HE and users very quickly.

Though the export pipeline may be different and currently requires 3ds Max or Maya, the format is highly optimized to reduce high quality models down to KB's.
