How not to break licence laws? I have an idea for a game. Also I have almost everything worked out considering coding. What interests me the most is how can I know if that game can be published. As it would be for iOS and android, these markets are of the geratest interest for me. I found on apples store something similair to what I would make and it's published by some big game developer. How can I be sure I am not breaking any laws when publishing the game? Can I make a game like board game 'Risk'? I don't have any knowledge considering licencing. This game would be avaliable for free, with an option to donate, so money isn't my objective (but it won't hurt)
