You can build a million bridges and they will never call you a bridge builder. You can save a million lives and they will never call you a life saver. Cheat once and you are a cheater forever.
But you are young and easily forgiven. It's just that this game is designed to be easily accessible to 10 year olds and there is NEVER any time in the game where you would HAVE to cheat. If you can not take on Nevin the Silent in Beckett's Quarry without cheating then either form a crew or wait until you can. That's the way the game is designed.
But publicly announcing that you are looking for a cheat and then claiming that you are not a cheater fails the logic test. If you are indeed NOT a cheater then you have no need for a cheat.
Anyway, good luck in whatever you decide. Fair seas, mate.
