I don' t know if I am missing the greatest pleasure of my life. I am no fan of computer games. Some guys forget themselves and forget day and night when they play games. For example, a colleague has been playing since 1 o’clock this morning and now it is 7 o'clock. He is still commanding his army of little people to attack strange-looking animals. Some games could be fun, 1 admit, and it is therefore understandable that such a game catches players. For example, games like Red Storm or some role-play games, you do something and try to outwit(智胜) your computer. You get some fun out of these games. It is understandable that such a game pushes you into a pitfall(陷阱) of pleasures. But some games look quite stupid and simple. Again for example, my colleague has been interested in Stone Age, a cartoon-like game rooted in prehistoric time. The game is well made, full of strange people and animals and you can play on line with partners. You can have reference books to study so as to shortcut your rivals(对手) and increase your own conquering power.

I believe some kinds of games are really created for adults. But seeing these adults play the simple games with such interest, I just wonder if there is something wrong with me and if I am losing the greatest possible fun of my life. I ask why I don’t bother playing such games and why I seem to have some aversion(讨厌) to such games. I have no answers. Certainly computer games is no my idea of a good time. I would rather listen to some music or read a book. Take music for example. Good music tops my list of pleasures. Nothing could beat music, all in a harmony of sounds and emotions. But how about games? Why am I so strongly biased(偏见) against such games?
