I always create a story about the family I want to play with when in CAS, then make them. I also throw lots of parties, and since I got deluxe upgrade in the store, is even more fun, I give lots of black and white bashes and incognito costume parties, I created new lots for community (those from EA are boring), you can get them in gallery or in TSR, modthesims, etc if you are lazy.
Then I go to those lots and make chaos happen, I invite sims that don't like each other, I try to up the game, etc. Sometimes I go on dates with 2 different people in very short time and once one of the other guys appeared in the middle end of it and it was very funny lol.
But I guess you have to create different sims (mixed traits and delete most of all the boring EA families). Download people from gallery without checking the traits and mix them in families and see what happens is fun for me too.
I choose to play a person opposite of me in real life and it is pretty fun too lol.
I create rivals too, for example, as neighbors of Landgraabs I made a rich family (with cheats for money) and they kinda compete and brag lol, some are snobs, they throw parties and invite those Landgraabs, but can you believe everybody but them come to the party. I get so angry.
I also downloaded custom traits to increase variety and the mod "More Autonomous Interactions" and "Emotional Overcharge" from modthesims, that makes other sims react more strongly to things (less blandly).
For me Sims 2 Base game was the most fun, Sims 1 base game got boring quick and Sims 3 base game was always kinda bland to me even with some expansion packs.
What annoys me about Sims 4 is that I don't have enough space in the worlds to put more families and people to fight and make friends, that sometimes make the game boring.
