framework for engine

is it possible that I make an engine on top of monogame? I have to declare any license or something like that?

It is absolutely possible. MonoGame is not an engine itself, but a platform-agnostic framework to access the graphics, audio, input and other features of the target platforms. There are other engines out there that are built on MonoGame already.

There is no license declaration required, but a mention or acknowledgement would be nice.

Thanks man, I think a mention or a knowledgement is necessary because MonoGame is awesome :smiley:
