I agree, Rift and WoW would be higher on my list as well, but neither of them seem to be doing all that great. I took it with a grain of salt when I read that thread recently that had estimated log-ins for various games. Since Turbine has stated they do not share that information, then I can only conclude that the chart is very poorly put together. Nevertheless, it did surprise me that those "guesses" pegged SWTOR as being higher than LOTRO. That game has been barely above the waterline since the day it launched. At least LOTRO has had a good number of solid years to build a dedicated player-base.
Rift did indeed have a lot of people, at least on whatever server I was on. I honestly didn't care for it too much. At first I was drawn to the rifts like a kid in a candy shop, but eventually they became a nuisance, getting in the way of my other objectives. I only just got into the second region before I quit.
LOTRO is the only game that I always come back to, and I think that says a lot, for me personally, and I wasn't even here at the beginning (though I sure wish I was). Do I miss my early days? I sure do. Even I can see that not all the changes have been for the best. But then I guess it just reminds me of something Frodo said. He saved the Shire, but not for himself. He couldn't just go back to the way things were. He'd seen too much, experienced too much. In a lot of ways, that reflects my time here on LOTRO. We've come a long way, and there is longer still to go, but the nostalgia that many of us share is just that -- nostalgia.
