Why just 18-30? I'm 40 and grew up in the 80's --- pretty much when home gaming started. I don't have the time to play like I used to, but I still play once in a while, and have been involved in a few MMORPG's (EVE Online, WoW, LotRO). I tend to play more games with a pause button, or family oriented games now, but I understand the line between gaming and real life. Not that I'm running for office, but I have no problem with the fact that someone that is plays games. There are plenty of people who work at high levels yet still find time for recreation. In fact, I'm willing to bet most people working at high levels need to find some sort of recreation, whether it be Golf or WoW, people need stress relief.
My mother is 75 and still plays super Mario Brothers. Before computer games, people played plenty of board, card and dice games. I understand they are going after this person based on what they are in the game as much as the fact that she plays it, but I know for a fact (based on my own experience) that what you do in a game does not reflect how you handle real life situations. At least for people considered normal, it shouldn't.
