Despite how expansive the game has become with so many added features, it feels small. The expansions feel like they have little to do with each other or with the main game. They're just a one-and-done at a time deal.
So many big activities feel small because they're tied to a certain lot type, and you can't have two types at once.
There's also no society in this game. No attraction system, no friend-scoping system, sims in any relationship have no build-up of feelings despite the actions they perform.
If you remember the movie Pleasantville, The Sims 4 (until 2021 so far) feels like that grey, monotonous place. A society system, relationship system, and enabling multi-lot types might save it.
