Is winning the most important aspect of playing a game?

Everyone has the experience of playing games with others. Why we play games? One obvious reason is that we want to relax, to enjoy our life, to have fun. Anyway, some games, including tennis or badminton, will produce the winner and the loser. In my opinion, I disagree that only the winner has got fun.  

The first and far most reason is that the purpose of playing games is to escape from your boring data, or office to smell flowers. Wining or losing has nothing to do with your fun, because it is not your job, it is just a game. For example, we students have to spend ten to fifteen hours in lab or in reading textbook, when we have a chance to play football with our friends, who will really emphasis on the results. Everyone has got fun.  

Another reason why I contradict the title statement is that we can learn something useful by playing games. We may take long running as an example. As we know, the last part of long running is hard to stand. Even though you lost the game, you also learn that persistence can lead to victory, which will do well to your career.  

Finally, some games such as football help shape your body in spite of loss. So, why not depress?   Taking into account all of these factors, we may safely arrive at the conclusion that both wining and losing in play games give us fun.
