This is simply amazing. It appeals to all sorts of people:

"Murderers" -- you can kill your Sim in dozens of ways, but that isn't the good part.

Architects -- You can design and build your Sim's house and see how they like it.

Romancey-people -- Yes, there's romance in the game -.-

Casual gamers -- This game may appeal to many types of people, but even casual gamers such as myself are not at all left out.

The only reason I didn't give it a ten is probably the minor lag and occasional bugs. With a lot of expansion packs, especially Supernatural, the lag spikes and loading times take about twenty minutes.
