The cheat code is a lost art. Back in the day, codes were used as debug functions or inserted as Easter eggs. These weren't necessarily intended for players, but gamers began uncovering them and enhancing gaming experiences nonetheless. Nowadays, game testing is far more sophisticated and debug codes are seldom left inside a finished product. In addition, developers have become far less interested in hiding Easter eggs (at least in the form of cheat codes.) No one really wants to insert any function into their game that will make it easier and thus reduce play value.
