The way of playing The Sims is practically parallel to playing any game from the Metal Gear Solid series: You have one of two options to play the entire game. You can either do the Solid Snake method, the way the game was meant to be played, by swiftly moving by and sneaking by with as minimal casualties as possible. Then there's the "typical gamer" method, which is shoot everyone on sight, don't give a fuck about alerts because you'll get out of that situation anyways. It's the same, you cheat to get by the game and simply enjoy the game, or you play it by the rules to REALLY enjoy how much intricate and time is put into building the game. It's whatever you want to do.
TL;DR: it's up to you.
Cheating can make the game assloads of fun. Quick backstory: Sims cry and piss their pants when they see ghosts. Once on Sims 2, I invited/spawned everyone in the neighborhood in this room I created to fit everyone. I killed one of them off, which spawned a ghost. Once the ghost spawned, there were roughly 40 Sims that had simultaneously cried, and pissed themselves. Then I watched the hot maid clean up every damn bit of it.
