I do think changing the password is a horrible waste of you guys' time. Because no matter how many times you change it... it's going to take SOMEONE out there just as little time to crack it as it took you to change it. Not saying I'm going to... hell I don't even have ACCESS to the game yet because the steam version is all that's available... but someone will, and you can't stop them. No amount of appealing to common sense, warnings, threats or otherwise will stop them from cracking the password. Make the password 7000 characters long and people will STILL crack it within the first few hours.
I think cheats in single player can be fun for people who have already finished the game and I think sometimes they can let people avoid the parts of the game they don't enjoy, which can be fun for them too... but regardless of the attitude towards cheats... changing the password is foolish and a waste of time.
