The Sims 4 is a life simulation game, similar to its predecessors. Players create a Sim character and control their life to explore different personalities which change the way the game plays out. Sims can multitask such as talk while doing a task. Sims' moodlets also change the gameplay. For example, a Sim can do a task while being either angry or totally excited. Similar to previous Sims games, player-created challenges abound. One of the most prevalent is the Legacy Challenge, in which players create a single Sim and try to make its family line last for ten generations.
