Here are the details directly from The Sims News:
The Landgraabs are back, still living it up as the richest family and staking their claim in Oasis Springs. We’ve brought Malcolm back during those awful awkward teen years, complete with a dastardly snobby attitude. Though Geoffrey is trying his best to be the good natured father Malcolm needs, will Nancy’s scheming ways lead Malcolm down a darker path? Either way we’re sure this historic family will provide lots of fun and mischief in The Sims 4.
Then we have the Caliente household with our two favorite sisters Dina, Nina, and their mother, who has been re-imagined as the attractive and vivacious Katrina. Katrina has ignored her better judgment and let the infamous womanizer Don Lothario mooch his way into her house and quite possibly her heart. Don’s eyes are on Katrina for now, but how long will it be before Nina and Dina are lured in by his charm? Will Nina decide to steal Don away from her mother? Will Dina finally earn enough money to get her own place and get away from all the craziness? All we know is that it won’t be long before sparks start flying!
Johnny Zest is an ambitious new character we like to introduce. Disowned from the Landgraab family when he dropped out of school, he now hopes to find his own fame and fortune as a standup comedian. He’s learned the hard lesson that when the Landgraabs cut you off, they cut you off all the way! Living in a trailer, blessed with the Landgraab looks but without the name or the money; will he make it to the top to show mom and pop he had what it takes all along? We’ll leave the fate of this black sheep in your capable hands.
Finally we’ve got a new batch of youths known as the Roomies. Your typical sitcom setup with ‘J’ (Jameson) the body building hunk, Gavin the gentleman muser, Mitchell the couch potato bro, and Zoe, that girl next door who is actually right where she wants to be, having fun with the friend-zoned boys.
The Sims 4 will release September 2 for PC. Which is your favorite Sims Family?
