On FB and G+ games, they don't allow you to modify the permissions for the games. What if I don't want to give you my email address and all of my info?

Checkboxes would be nice, and the game creator will then have the chose of refusing me if I don't give enough info.

For game creators, don't ask for permissions that aren't needed (don't ask for any). If I like your game, I will tell my friends. If I want to have you email me, I will subscribe to your email list. Don't make all this bs the cost of admission. I just won't pay.
