I understand that and would also prefer open source, but that is not possible, at least not for the Zorro core. Some of the software is under license, and we also have been paid for the development and thus can not freely give away the source.

However, we will make Zorro as open and extensible as possible. We have done the same with Gamestudio - it is not open source, yet users can add functions and improve or extend all parts of it.

Zorro is here to stay.
