Little Kitty Big City, for me, exemplifies the perfect Gamepass game. It's short, it's simple, but still loads of fun.
It's a really cozy game that still manages to pack in enough content to feel like a meaty game.
I didn't 100 percent all the sidequests because some of them were a little tedious, but a lot of them were pretty good.
Highly recommend on Gamepass. Maybe if you wanna buy it though, wait for sale.
