Toca Life World is the big one: the sandbox that connects the Toca locations into a single place where your stories happen. Build the house you actually want to live in, spend the afternoon at the beach, or open a pet daycare and see who shows up.
Nothing here tells you what to do next. You drag characters and objects around, they react, and the story is whatever you decide it is. That freedom is why kids play it for hours and why it stays interesting after weeks.
