Leadwerks vs uScript + Unity3D

Good API tutoials, workshop elements which can be loaded from steam.

Has an acceptable 3D map editor that is easy to use.

Leadwerks's flowgraphs 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.

It makes game developing much easier if you have someone backing you up when you run into a bug or other issues, and get replies within hours .

Standard edition of Leadwerks costs 92,99€. Additionally, it often goes on sale on Steam.

The terrain editor allows sculpting, paint, vegetation placement and importing of external maps. Especially the painting is done very well and can lead quickly to very professional looking results.

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.
