So, each CD ships with a unique key, but it is quite possible to create non-unique keys.Furthermore, to stymie crackers, it's my guess that there are actually 2 different algorithms used to verify keys: one for the single player game, and another for. For each CD they package, they put in the next serial number and print up a sticker with the key generated with that serial number.
What happens is there is some (ostensibly one-way) algorithm to compute CD keys based on a seed (e.g. Since I bought the game to play on, this is not a viable option.Do you think each CD has a unique key built into it? No. It somehow checks for a valid CD key and if your key fails, you can't play a game. Quote:The problem with generating a false CD key is that will not work.
