City Living !
I had just started playing TS4, and when the trailer dropped with that Teagan & Sara song, I realized this was exactly my jam, the colors, the vibes, the urban setting, exiting the bubble of your house to actual life, instead of a void and having to travel to do anything or see anyone.
(Well except for Uptown but it works there)
It's still my favorite town to this day and the one I play the most in, prepped apartments for the infant update just last week. Every time I play elsewhere, I miss San Myshuno.
City Living + the toddler update dropped soon after was what really made me fall for the sims, unsure I'd have played for long otherwise.
Nothing since then came close to hyping me that much.
