TS1
Pros: It was new and exciting as the first of its kind (nostalgia)
Personality points/interests
The personal biographies for the sims
Angry sims were hilarious
The expansions were fun
The music
Sandbox-style play
Cons: No aging
Babies were objects
The bugs - I hated those things
CAS very limited
TS2
Pros: There is so much I love about this game I couldn't begin to list it all. Just a few standouts would be -
The dancing. Sims could slow dance, Hula, Slap dance...all the different dances but especially the Smustle, which is the greatest Sim dance ever.
The romantic interactions, sims could actually cuddle.
Sims would get jealous/angry/sad and stay that way for more realistic periods of time
The children and toddlers were adorable and their play animations were great
The memories
Chemistry
Neighborhoods had more than 4-10 lots
You could create your own neighborhoods
So many ways to die
again, I could go on forever...
Cons: You couldn't really build a good basement
Limited CAS
TS3
Pros: I didn't care much for this iteration of the Sims, it is my least favorite and I didn't play it much.
It had a lot of the things that Sims 2 had
There were improvements to the building
More variety in CAS
Cons: The Sims look bad, in spite of the CAS having more diversity/options
I did not care for the open world
It was difficult for rotational play
Babies are objects again
It was more goal-oriented play and less sandbox-style
TS4
Pros: The Sims look pretty good and CAS has a lot of options
The basement tool and building, in general, is awesome
The multitasking is great
The pathing of Sims is better, less getting stuck
The expansions are good
Clubs were a great addition, making it easier to socialize
The vampires are much improved
It strikes a good balance between goal-oriented and sandbox-style play
Cons: The romantic interactions are sorely lacking
The dancing is lacking - no slow-dancing, no Smustle!
It is too hard to kill Sims
Babies are objects
Sims' emotions are too fickle, they get over their spouse cheating in like 15 minutes. The only one that is close to good is grieving after a death.
You can't see the needs of the pets or control the pets
The neighborhoods have too few lots
You can't create your own neighborhoods
