Battlestation: Harbinger Piracy Rate

Just a wondering... Could you set up ads in the game, with an option to buy them off? I really hate ads in games, but you could always be creative about it, say take the ads off when they buy the game. If you were to build it into the game, then hopefully even the pirated copies would pay you something.

Just a suggestion, even though I bought the game and would happily buy any new releases after playing this one.
