i usually only cheat with games i've beaten. Best example: Oblivion. I just don't want to go trough that entire tedious tutorial level when i start a new character to try something. I KNOW i can do the tutorial without even trying, even on hard dificulty, so why bother. So for that part, i just boost my thwaking skills to maximum for a lot of damage and run for it, instakilling everything on my way there. The skills reset anyway, so it's not a problem.
I do get the idea that the better you get at gaming, the less you cheat, because you don't need to.
