Description & requirements
The Sims 3 is built upon the same concept as its predecessors. Players control their own Sims in activities and relationships in a similar manner to real life. The gameplay is open-ended and indefinite. Sim houses and neighborhoods are entirely in one continuous map. The developers stated, "What you do outside your home now matters as much as what you do within." One of the biggest changes to the franchise is the use of rabbit-holes. Sims aren't allowed to go inside the majority of city buildings; instead, they simply disappear inside for a certain amount of time—a feature known in video games as a rabbit-hole—while the player is given very basic choices on what happens inside without actually seeing it. The previous installments had many types of locales in which sims could cavort. For example, instead of walking a sim and her date inside a restaurant and watching the waiter serve them dinner as they nuzzle each other at the table, as in The Sims 2, the player now waits outside while getting little text alerts about the sim's activities.
