I may or may not have downloaded a bunch of townies from the gallery like Sleeping Beauty, Snow White, Captain America, Will Smith, Ariana Grande, Beyonce, Lady Gaga, the characters from Inside Out, the cast of Ocean's 11, Harry Potter and his friends, etc etc--basically filled Newcrest up with cool houses and interesting characters/celebs. Then I created three female sims: The psychopath, the golddigger, and the innocent one. I also made another household with a male cop who would trap people in a room with a cowplant until the died and harvested their life essence to stay immortal.
Four generations later and the psychopath is married to Aquaman after killing his wife (Kida from Atlantis) and their kids, has four kids with him, and is currently trying to poison him. The golddigger has at least 18 kids with the Grim Reaper, Thor, Captain America (Whom her daughter with the Reaper ended up marrying), Vlad (to steal his money of course), and a whole host of others. And she's a vampire now and completely immortal but she's living in Sulani... The innocent one ended up marrying Princess Jasmine (Stole her from Aladdin) and they adopted three kids and two dogs, and lived happily ever after until they died from old age... their great grand kids are now involved with the great grand kids of the other two OG sims. Every once in a while, the cop shows up and causes some mischief in someone's life to keep things interesting.
It's my best save because I'm not worried about anything being perfect (besides the perfectly manicured graveyard) and it's so much fun causing mayhem everywhere. I burned the Landgraab mansion down with a SummerFest Firework Show Spectacular, convinced Alexander Goth and Luna Villareal to get married, trapped one of their kids in a basement to paint forever, forced Snow White to take care of seven toddlers (which all got taken away because she was not a great mom), then had her evil stepmother force her into marriage with The Hulk, with whom she actually ended up falling in love with, but then Black Widow got super jealous and killed her and the Hulk was so sad the he instantly turned into a ghost (Totally not with the help of MCCC ;) and now is the keeper of graveyard #3.
There's a lot more that happened but the drama never ends because when I run out of characters, I find more on the gallery or pull characters from my other saves to participate in the ruckus. It's nice not being restricted by rotational play
