Some of us grown ups have wonderful lives yet still find plenty of time to have fun playing VMK.
Some of us grown ups have already had wonderful lives and have retired from them thus leaving plenty of time to play online games.
Some of us grown ups have illnesses or disabilities that prevent us from leaving the house much so being on line is a major part of our daily life.
I fit into all three of the above categories. I've been playing online games since I was in college. I don't work anymore but sitting in front of a computer for several hours a day is second nature to me so I started playing online games. Even though I spend a lot of time on the computer, I still find plenty of time to have hobbies and spend time with my family and friends. And you know what? My doctors encourage me to play certain types of computer and online games. Some games help preserve your mental acuity, others help you have some sort of social life when you aren't able to leave the house, therefore keeping you from isolating yourself. Those games can be very helpful to me at times.
