Ranked in these QuestionsQuestion Ranking
Pro Allows creating 3D apps and games without programming
Pro Available on Steam
CopperCube is available on Steam It was Greenlit.
Pro Easy to learn and to use
Pro Native WebGL support
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.
Pro Good 3D editor
Includes easy to use 3D editor for quickly clicking together 3D games.
Pro Exports to irrlicht
It was also written by the founder of irrlicht, although it is not open source.
Pro Good terrain editor
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.
Pro Fast prototyping
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.
Pro Oculus Rift support
Supports both DK2 and DK1.
ct.js is bundled with examples, docs, and easy to follow tutorials. Documentation and tutorials are available in a side panel on every screen.
Pro Skeletal animations with DragonBones support
You can import skeletal sprites and animations from DragonBones, which is also free. Skeletal animations are added to objects through code; developers can listen to marked events in animation, and ct.js automatically associates sounds in a DragonBones project with the game's assets.
Pro Good code editor
The built-in code editor comes with error checking, type checks, code completions accompanied with docs, multiple cursors support, and other modern features.
Pro Open source (MIT)
This means that no one will ever put any features behind a paywall and that you can reliably use ct.js in any projects without worrying about licensing. And you can hack on ct.js!
The repo is at https://github.com/ct-js/ct-js
Pro Tileset support
ct.js supports tiles in rooms, including collision checks and some extra editor tools, like bulk migration to a new tile layer or shifting by an exact value.
Pro WebGL and WebGL2 support
Starting with v1.0.0-next-1, you can now write WebGL games. WebGL support is based on Pixi.js.
Pro Modular approach
ct.js has a "Core" library that provides basic drawing functions, room and asset management, and mouse interactions. Any other functions are added to projects as "catmods", or simply modules. These modules can be enabled or disabled in one click, and can inject their code in different game loop stages, e.g. after drawing all the objects, leaving a room, or when a new object is created.
Pro Applicable to most genres
ct.js aims to be a general game engine and provides tools in making games of any genre.
Pro Dialogue and visual novel system with support for Yarn
A module ct.yarn allows developers to import a YarnSpinner project to create branching, data-driven dialogues and visual novels. An example is also bundled with ct.js.
The dialogue tree is made in a separate app, though.
Pro Real-time particle system editor
v1.3 brings a particle system editor, which displays a preview sprite for proper attachment of emitter to visual elements, and allows combining more than one emitter with different particles into one effect. With these, even the creation of complex, multi-step effects becomes easy. The editor comes with dozens ready-made textures for faster prototyping.
Con Tile editing is a chore
No live brushes with automatic corner drawing, no fills or rectangular/linear placement. All tiles should be placed by hand, with a "Shift" key to place multiple tiles at once. This will make you ragequit if you want to make sophisticated RPG scenes :D
Con Slower than native games
