Pros
Pro Easy assets
it is very easy to import your own 2 dimensional assets
Pro Very easy to use
relies largely on drag and drop elements and has been used to create notable high quality 2d games such as DLC Quest
Pro Automatically generates nodes for third-party script assets
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.
Pro Versatile flow diagram script model
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.
Pro Generates C# source code
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.
Cons
Con It's dead
It is not getting updated and Microsoft does not recommend using it anymore.
Con Limited platform support
Only supports Xbox 360, Windows and Windows Phone
Con Not that easy to use
It's a lot more complicated compared to something like Playmaker. Same tasks take a lot more time.
