...After a few months of research, I came up with the following list of projects:
-Ogre3D
-Bullet Physics
-MYGUI
-OgreVideoPlugin
-OgreOggSound
-OpenAL
To stick with this idea, I recommend the use of some Tools, such as Eclipse, Code::Blocks and msys2/MinGW64 for the development environment.
GWT is an flexible and object-oriented 2d game engine. It uses Code::Blocks and is based on SFML2 to give the ability to port your code to multiple platforms.
With the integrated all-in-one tool for game resources it's possible to develop games in a short time.
And it's open source! (license coming soon)
