I don't find caring for a Sims needs particularly stressful, but that might be because I've played it so much. I know my sister finds that it's suddenly become stressful since she switched from PC to Playstation, which I find weird. Can it somehow be harder on console??? Anyway, it's the only game I've used cheats for, though not out of some posh idea that that's a bad thing. It depends on what people find fun. In the Sims I've sometimes used money cheats, depending on the story. The thing is, if you want to make enough money to buy a decent house, you'll never get there just by getting to the top of a fancy career. You have to either grind and grind on painting or writing or you have to, like, have a store that specializes in only selling one very expensive violin. In the real world people don't buy houses like that, they take a loan. And sometimes I don't feel like playing the story of grinding for cash, sometimes I want to focus on other aspects, like a career. So sometimes in my "stories" I decide that they happened to have a rich uncle or that they took out a loan for the house or whatever. It's not a goal oriented game, it's a story oriented game. However, it makes a difference that it's a single player game, so I'm not effecting the game of others. I figure if I was cheating to make myself super powerful in a multi-player game, where others were effected, that would make a difference! I also think that some games would get pretty boring if you cheated your way through the levels, but to each their own.
I like that in Planet Zoo, the simulation game I'm currently hooked on, there's franchise mode, where you have to make a zoo run financially, and then there's sandbox mode, where you have infinite cash and can just be creative building whatever your heart desires. I figure that's a bit like using cheats in The Sims.
