- The sims world adventures
-geared towards: Young adult-elder sims.
-new content: Very high.
The sims world adventures gives your sims 3 new destinations to visit: France, China, and Egypt. Theses destinations all contain a city filled with local sims and shops with exclusive items, and the outside area that is filled with scenery, (parks, ponds), and tombs. Each city has different skills and items associated with it. China focuses on martial arts, France, focuses on wine making, and Egypt has snake charming. All cities also have their own food recipes, recreational books, and 2 songs your sim can learn. Apart from hanging in the cities, your sim can go on different adventures throughout the many tombs that are in each place earning simoleons, gems, and other rare treasures. All ages get new hair (not sure about toddlers) and children-elders get new clothes. Useful expansion if you like exploration and adventuring.
- Negative aspects: Vacations are not geared towards larger groups of sims, with adventure focused gameplay. Doesn't add much to home-town.
- geared toward: all ages
- new content medium-low
The sims generations is all about adding more to the different life stages of the sims, especially children and teens. Adults get one new interaction with toddlers and toddlers get a a few new objects. Children get pranks (whoopee cushion, shower dye) and make belief play. Teens get pranks and mischievous behavior (egging houses, teen parties, mood swings...) Adults get midlife crisis and bachelor parties, elders get canes. Certain interactive objects for children and up such as hopscotch, slip 'n' slide, chemistry station new hair and clothes for everyone. Useful expansion if you feel like teens and especially children are boring.
-negative aspects: Feels somewhat like a glorified stuff pack because you mostly get objects and interactions and no big game changes. Also no new town.
- Sims 3 pets
Geared toward: pets of course.
New content: High.
The sims 3 pets adds dogs, cats, and horses into the game as well as smaller minor pets such as birds, and a variety of rodents/reptiles. Pets are fully controllable with their own interactions for objects, pets, and sims.

New town called Appaloosa planes. Some new hair and clothes for children to elders. Useful expansion if you want pets. Way better than the sims 2 pets.
Negative aspect: Not much new content for sims themselves.
Sims 3 showtime:
- Geared toward: young adults-elders.
- new content low:
The sims 3 showtime gives your sims the ability to join one of 3 careers singer, acrobat, or magician.

Sims also get a few new objects such as karaoke, pool table, skeeball, spinning bull, and more. some of the objects can't be used by children. New hair and clothes for teens-elders.
