The Wii version of MySims Party takes a departure from The Sims franchise and the other MySims games and begins with a character moving into a run-down town with a mayor desperate to bring residents back. The player's job is to enter festivals and win to bring new people into town. Players must collect points during these minigames to gain new characters and monuments and in return are given new playable characters and outfits for their Sim. As the town's population increases, new areas are unlocked.
The player can interact with citizens by talking to them. The player character can be customized in many different items. Unlike other games in The Sims franchise, the Sim does not have needs or wants.
In the Nintendo Wii version of MySims Party only the Wii Remote is used to play minigames.
