Most great hackers started while they were still kids. If he was adult hacker he certainly wouldn't waste his time here.
Most of the people having the skills to do this are not hackers but security experts. It's about the same thing anyway. Thing is, I believe most of these guys learned their job at college. Okay you need self education to keep in touch, but there's no reason so many of them should be passionate teenagers.
Besides, a lot of cRPG players are in their thirties. And I bet it's a lot more than in many other action multiplayer games.
