Hi,
Currently I’m working on a new game and I decided to create it nicely scalable and easy to modify later. This resulted in creating a simple library which contains classes to help organizing structure of the game (via nodes objects) and helpers for most common operations. It’s in early stage now and I plan to develop more features as the game development progress. I’m not trying to compete with any existing frameworks but create lightweight library to avoid massive boilerplate code and chaos 
Feel free to fork, contribute, express your opinion.
You can find the library on github here: BeetrootSoup.MonogameToolkit
