Big deal? I don't know. I just realized that I spent so much time on it and there are times that I my schedule got affected by it. Ok, i can almost hear those who thought that I must be nuts to be playing a game at my age and status. I don't think there's anything wrong, unless there's a label that says "for children between the ages 3 to 9". In my class in urban planning, even my professor asked us to play SIM CITY to get a good grasp of urban planning.
I remember when I was involved in a youth club in Manila. One time we had an excursion with grade school kids. I was seated at the back of a van with two grade 2 students and I was amused at how they spent their time while traveling. They were playing a game, but a virtual one. Each of them has a particular character and they would exchange roles or actions, depending on what the other says. One kid would say "I will attack you with this weapon! and you will be thrown away!" The other kid would respond: "I will use this gadget to hold on to something and throw myself at you with this weapon"... and so on...
Other than Nintendo's early games like Space Invaders, I don't really play much in computer. I often wonder what goes on in the minds of these kids.
There are many reasons why adults play games like this one. I think that the most important reason is that the game is an outlet for people who get frustrated over their desire to control things in their lives. In games, you have more control
