True, I had forgotten about UO, but for the sake of the argument I don't think it really matters. I don't have numbers ready, I had always seen EQ as the bigger mainstream success, could be wrong. Also was a bit before my time, I didn't pay sub fees for my games until 2004/05ish.
Edit: I didn't actually want to say that EQ invented it, but I had phrased that badly.
