Pros
Pro Versatile flow diagram script model
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.
Pro Built-in level editor
Has an acceptable 3D map editor that is easy to use.
Pro Handful of Prefabs and Scripts
For example, you take a model (e.g. torch), add a light source to it, add a particle generator (for fire) and save it as a prefab (one file). Then this prefab can be used to add many torches with fire and light.
Pro Standalone executables
Can create single file executables without the need to install other libraries, run time environments, etc.
Pro The syntax is very beginner-friendly
Pro Same code on Windows, OS X and Linux
Same code can be compiled natively, without any interpreter for OS X, Windows or Linux, using the native GUI toolkit of the OS
Pro Many integrated features
Many libraries available without additional installations : 2D & 3D, database, network, sound, xml, JSON, http...
Pro Allows to program at a lower level than most alternatives
Pro Lifetime license
Pay once, use forever.
Pro Constantly updated
Pro Supports ARM in addition to x86, AMD64 and others
Pro Can compile to plain C code
Pro Grest user community / forums with the developer very active
Cons
Con Very buggy
Leadworks is a not complete, it's a work in progress. As such many parts of the engine are clunky, especially the level editor.
Con Documentation and support are limited for non-coders
The flowgraph editor can be used with free script assets to build games without writing any code, but this is not directly intended or encouraged by Leadwerks.
Con Highly misleading advertising
Con Limited free version
Free version is limited to 800 lines and can not create DLL's.
Con Some bugs are present on the Linux platform
Con Slightly bogged syntax
Sometimes the syntax bogs down, just a little with long procedure names and such. A truly minor issue.
Con Not RAD
Not a RAD environment.
