For commercial Print and play game, you generally don't want to give the rules for free on the internet because that is the most important things they need to play. If they have the rules, there is no need to buy the game.
As some people suggested, I could do a video review of my game, but that would mean exposing the rules of the game.
Of course, I do not need to go into the details and they don't need to know the content of every card. That could prevent the user from making their own game without buying it. But again, that only works if you have a lot of unique components in the game.
Do you think it is a good idea to do a video review of commercial PNP game even if there is a demo available or do you think it is too risky of being ripped off?
I just thought that I could do a video review of the demo game and explain rapidly what will be different in the real game. This way, there is a video review for those who are more visual and it explains nothing more than the demo rules already available.
