I am mostly interested in the initial presentation and the continued development of Facebook games. I have played roughly 35-40 of them and continue to invest time in new ones to see how the field is expanding. At one point, I considered it research because a friend and I were developing our own browser-based RPG with a Facebook release planned, but I think those plans hit a roadstop when both of us got bored. We might pick it up sometime very soon though.
