I love me some cheats to start off GTA with. I'm usually this way when I play a new GTA...do the opening mission, then go around doing my own shit for awhile. Cheats help with the fun. Afterwards, cheats go off and it's time to do the story.
What do you see, when you look at me? That I'm angry? That I could hurt you? It must be my eyes...creeping along your body, you can feel the death waiting for you in my eyes.
