As a Canadian we tend to notably get lumped into North America/US. I am not incredibly offended by it, mostly because the Sims is a parody of many things. Simlish is a type of gibberish for example, many/most names are not meant to really be true/authentic names.
But I can see the frustration that the game is favoured to the US, US players and US culture/locations/etc. That is probably why I love it when we get Asian and European themed content. And I also favour fantasy/science fiction themes—so I like the occult worlds too. But the real world is made up of more than the handful of the content themes made.
In Sims 3 I loved giving my main Sim Asian hidden culture trait, and spending so much time in the Adventure worlds. I spent more time in those worlds than most of the other worlds (I mean Midnight Hollow, Monte Vista and Oasis Landing as much as or slightly more). The rest of the worlds not so much.
In Sims 4 as a new player with so much content to still catch up on, I do shy away from typical North American based worlds/CAS/etc.
