The 1992 version of Prince of Persia has the most useless copy protection ever. Level one is the only level included in the demo, so the copy protection kicks in when you win level one and try to play level two. When you win level one you get chucked inside a room with about a dozen potions. A dialog box comes up saying "drink the potion matching word X, line X, page X in the manual". Each potion has a letter above it. The stupid thing is that you get unlimited tries, and each time you have almost a 10% chance of drinking the right one... Often it only takes a few guesses to get it right. About 10 at the most. Anyone else encountered stupid/useless copy protection?
