I think it's safe to say that there is not more than 2 Million active "accounts" currently. I base this number of of people sleeping, etc, away.
Of that two million probably half is bots, so lets say 1 million active players. I base this on the post bot nuke numbers of several months ago - I don't believe that the game has doubled in popularity since then.
So in 10 years, Runescape has only been able to retain 0.5% of it's players!
That's a great number!
Although I agree that 200M is a cool milestone, they need to own it for what it really is.
