Same here. The 10-year-old rhythm keeps pulling me in. I log on, I know what to do, where to go, and I know the lore. It’s familiar. And I have three characters in the 80’s, 2 above 100, and a vault of stuff to help them all along.
But I know that there’s equally-compelling (or more) stuff out there. I left LOTRO for long stretches (up to a year each) to play Fallout 3 and Skyrim, along with early Witchers and various others. Now that I’ve been playing LOTRO for about a year straight I am figuring another vacation to play Fallout 4 and Witcher 3, at least. Maybe even Dragon Age, which I never got around to.
