So far I've talked to dozens of people about the game (who immediately or later purchased a copy) and 2/3 of those asked point blank "Does it use Starforce?" When I replied "The only copy protection is that registered users get free content updates and upgrades" - every one of them picked up a copy (several of whom may not have bought one otherwise, and one who bought one out of principal but expects to give it as a gift).
You're making a difference, and singlehandedly changing the way the software industry will do buisness. It's not just your stance on copy protection, but the fact that you are so vocal about it. None of this would matter anyway if, in addition to all that, you hadn't also delivered a fantastic game.
I'd also like to point out that there are as many pirated copies of Starforce games on the popular torrent sites as there are non-starforce games. You should definately talk to a lawyer about the whole linking to pirated software thing. If you were to take ANY kind of legal action, it make huge waves the likes of which we simply havn't seen yet (national television loves scandal).
