I generally only cheat to fix a problem, or to make tedium more convenient..... in Skyrim, for example: I've got 1000lbs+ of crafting materials. Yeah, I can pick it up and stagger slowly next door to the smith, do my crafting, and stagger back. Or I can "tgm", and run instead of staggering. Because it really has no effect at all on the actual gameplay. Or trying out a quest mod in Oblivion that turned out to have mass amounts of enemies with stupid amounts of HP... after killing the first half dozen (and demonstrating that I could do it without a chance of dying), I just "kill"ed most of the rest. They were tedious, hp-sponge, filler. (I can only assume that the mod designer uses much higher damage weapons & character builds).
I have used money cheats in games like the early Sim Cities or The Sims, to try goofy things with their construction tools that had nothing to do with playing the game right.
