AppCore for Unity is:
Think about gameplay, not code
Using visual programming and modern ECSA architecture, your games will not slow down and development will be much faster.
Allows you to prototype games quickly, with the prototype itself already being a "production reidy", it doesn't need to be rewritten before release.
Open source code, allows you to modify the framework to suit your needs.
Included under the hood
Everything you need for game development and lack in Unity is part of the framework and ready to use.
