So after thinking about the license stuff, i think i am going for MPL-2.0 for Delphinus. Which means you can use it(and compile it into) commercial software without making your Productcode available. You only have to share the source of Delphinus as Sourcecode in someway(as it states make it available, a link to the repository fullfills this, right?). I don't think restricting the project to much is good, but i want that people see what (and who) powers a specific mechanic in the background. Anybody has any concerns or things i overlooked here?
