I've made a Jezzball/ Barrack like game for practice. I wasn't planning on publishing it, but I think that it's pretty playable and interesting, however I'm concerned about legal issues for publishing a clone. Does anybody know is Jezzball copyright protected? How can I find out do I need to pay for the licence or can I just publish it?
I don't want to publish it with the same name and my game has a lot of different/new features, but essentialy it is a Jezzball clone...
How different must my game be in order to be original?
