Computer games are very popular these days．Some people think that it is bad．And others think that it is good．In my opinion, whether it is good or bad is determined by the players．
If one plays computer game properly in his spare time, computer games can be an excellent way of joy．For example, something impossible in your real life can come true in the computer games．You can drive a spaceship and travel in the universe．
Every coin has two sides．If one spends too much time on computer games, it may affect his eyesight, waste his work and study．And it’s bad for one’s health．
