I have two small corrections for the Ghost Guide and the Cheats guide.
For the ghosts guide, under the "causes of death-fire" section, the article states,
"Fire kills Sims. It can strike at any time with low level cooking. If a fire breaks out, and your Sim is in the vicinity upon the moment of combustion, there's a chance of death. There's also a chance of death when a Sim is fighting a fire. For non-brave or pyromaniac Sims, this can be a concern. It's usually better to call the fire department and take the loss rather than risk the death of the Sim. To kill a Sim with fire, you could have them stand next to a stove (wall them in so they have little choice on where to stand). If you put a food into the stove, then cancel the cooking action the burned food will eventually cause a fire. Sims that are killed by fire will be red in color."
It is possible to kill that way, but it is much easier to use a fireplace, as they survive the fire and can be re-used(death chamber anyone?) and can be more reliably and easily lit.
Additionally, it's easier to have a death room pre-built and use the teleportation cheat to send the doomed to their final resting place.-which brings me to my other submission.
In the cheats guide, under the "testingcheatsenabled" section, one cheat is missing. If shift-click on a sim that is not in your household you can click"add to active household".
When I first discovered this cheat, I was worried that it would lag or be complicated, to my relief, it works quite seamlessly.
Simply click on whoever, and they will instantly be under your control.
From there, the possibilities are endless. I had a vampire sim I made and I used this cheat quite often to put innocent bystanders under my control. I teleported them to torture chambers, prisons, stockades, and I even used them as my own personal maids, cooks and gardeners.
It's quite a nice cheat for a multitude of role-playing scenarios. Perhaps you have a military/law sim and you want to draft people off the streets to fill your ranks. Perhaps you're an evil/criminal sim and you want to kidnap people. Maybe you're a good sim and you want to remove another sim from a bad relationship, or take an evil sim under your wing and convert them.
I hope these helped, and if they were already listed, I'm sorry.
Have a nice day=)
