As far as I'm aware, no game in the history of computer games have being uncrackable.
From what I know, Hired Guns for the Amiga was never properly cracked, as it didn't hit you with the copy protection scheme until a good way into the game, and no-one caught it. Ofcourse this probably won't work these days. ELSPA and Co won't admit they're wrong regardless. Why would they?
You're probably right. I'm probably being a bit too idealistic.
