If your Sim uses the metal detector in the yard, he can find games made by EA games that were a flop. You can find Goldeneye: Rogue Agent and Urbz: Sims in the City, both commercial flops. If he finds them, your Sim will throw them on the ground and stomp on them, showing how terrible the designers thought the games were.
