Forced myself to take some downtime and went back to that tonight. Rufaniel's now level 58 and sloshing around the waterworks of Moria.
I do periodically wish I was into WoW so I could run around w/ sirfox in a more-vibrant-colors sort of fantasy world, but I'm loathe to pay the subscription fee for a game I'd play in fits and spurts at best. I have a lifetime sub to LotRO, so as long as I've got internet, I'll have access to that. (At least until it shuts down, but I'm pretty sure that's a few years away still.)
I periodically consider DDO just for the Eberron-ness of it, except that from what I gather it's not very solo-friendly, and also not very Eberron-ish, which is disappointing.
