Then with a real sport you don't just pay attention on one certain thing, you have to pay attention to possibly multiple things. You also have to train for the real game, which keeps you in shape. When you're playing the real game you can't pause it or even start it over, which means you have one chance. One more fun part is that you can be outside and you most likely wear a uniform.
Even though they are both very different they do have some things in common, like you have to know what you're doing otherwise you could win or lose. A good thing is that you can pay attention on what you're doing inside or out. On both only so many people can play at once. The best part is that you get to have fun either way!
