In the begging of the game when you design your sim, you will see the power level of a glove, shoe, and rench. They stand for Power, Speed, and Teqniuque. You might not think they are important, but they are!
These stats are important becuase they actually control the way you play the game! For example, Bus! Stop! minigame. When it is time to start running, if you have a speed with 5 blocks when you started, you will run really fast! But if you only have 1 block, you will go really slow! Another example is Gone fishin'. If you have 5 blocks of the power level, you will real in the fish easily! But if you only have 1, your gonna have some trouble catching the fish!
So you must make sure that you keep your stats as high as possible! Some Festible cards will help you raise your stats! Don't judge your stats until you see what their for!
