The Sims 4 is a life simulator giant that just keeps growing. These life simulator games can be great on their own for a while, and in the case of The Sims 4, there's definitely plenty to do. Once the player is used to the game, however, it can get boring doing the same tasks over and over, with no proper purpose. That's where the Legacy Challenge comes in.
