Go to the graveyard, and have the Sim steal male remains. Return to your house, and place them somewhere in your backyard.On the second day after putting the male remains in your home, a ghost will appear at p.m. You now have a 70% chance of a ghost or two, or even a whole party of ghosts visiting your house each night. Keep playing until you reach 5/10 level, which gives you the ability to "Play For Tips".
If you keep repeating the steps until each skill channel has been viewed, the Sim will keep learning the three skills as he or she goes on about their daily life, and four when doing skill activities.
With the "Writing" skill maxed out, you can make approximately 40,000 Simoleons every week, which is more than the 34,800 Simoleons you can get by purchasing all neighborhood businesses, and takes less time to achieve.
In three game weeks you should have a very high speed writing, 9 or 10 novels as best sellers, and 100,000 Simoleons.
To max out Moodlets and keep them that way, enable the "testing Cheatsenabled true" code. Select "Make all happy", and click the mailbox again, then select "Make needs static".
While the "testing Cheatsenabled true" code is enabled, hold [Ctrl] and drag the Mouse left or right to raise or lower your Sim's current motive as well as raise or lower relationships.
To do this with a roomie simply repeat, but no need to call the cops.
