My favorite is a tie between Late Night and Generations. I love Late Night because it added in vampires that were more involved than 2's with cool new abilities and a big city, and Generations well... y'all know why we love Generations! I really dislike Into The Future. Nothing about the future interests me when I'm…
I'm just going to stick with 3. It's clear EA does NOT care about older players who have voiced they do not like the direction the game is going in. Can't milk me for "micro" transactions if I'm not buying the new stuff.
Perhaps its just me, but I've never found a good time to use "Born Salesperson" and "Shy." The first trait because I guess I didn't frequent the consignment shop enough, and the latter trait because it kind of already exists with the pre-existing "Loner" trait in the game.
My game is heavily modded. From NRaas mods to Faerielandsims' retextures of all the hairs in game. I gotta have it all. I absolutely recommend using quality of life mods for the game at least.
