Some years when I was still a kid, I used to make use of cheat guides to play a lot of my games which I have access to them. I used it a lot playing most of my GTA games before GTA 4.
It all depends on the kind of cheats you are looking to use. I remember as a kid, my brothers and my cousin used to use cheat codes that would allow us to have every weapon in a game or have neverending currency in the game and that was a lot of fun if we had already completed the game using no cheats.
