Superpowers vs uScript + Unity3D

You can spin up a server and work with other people at the same time.

This isn't a 3D with 2D on the side type of engine. The scene-editor supports both 3D and 2D views, allowing ease of use no matter what type of game your making.

The community can develop and release their own plugins to add additional features making game development easier. All of these plugins can be easily downloaded in the app.

It's got a scene-editor, cubic-model creator, text-editor, 2D image / animation importer, and a very useful tile-map editor.

Games can be published to the web with good performance, and the game-framework utilizes TypeScript to make programming games a little bit nicer.

uScript's nodes are a visual representation of actual code blocks, and it takes advantage of C#'s reflection capabilities to automatically create nodes for any scripts it finds in your project, regardless of the source. This makes it inherently compatible with pretty much everything.

Custom nodes can also be created by hand, for cases where the automatically created ones contain more elements than they actually need.

Modeled after UDK's Kismet (the predecessor to UE4's Blueprint), uScript's scripts resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.

Nodes are translated directly to C# files in your project. This is great for learning to code, and also for advanced users who can use uScript for fast prototyping and then further optimize the scripts if necessary.
