Bioethics term project

My term project for my bioethics course consists of completing an ethical clearance document for my "dream project". I have chosen "Prevalence of addiction risk factors among Canadian online gamers". The study will NOT actually be conducted, but for the purpose of this assignment we pretend that this is a real project. I now pose to you several questions:

- What are some popular online MMORPGs (massive multiplayer online role playing games) and FPS (First Person Shooter) games?
- If you had the opportunity to be part of the research team, what questions would you like investigated?
- If you were a gamer asked to participate, would you being willing to participate?
- If Yes or Maybe, what conditions would you place on participating in the study?

I've made this public so anyone can weigh in with their responses.
