StrayKAT...
I passed on TES Online as well...and yes...I'm becoming a huge fan of the series(Currently making a run at Morrobliovion and I love it!) with Oblivion being my favorite. Specifically...what Martin Septim did...I had tears welling up. No, not kidding. I hope Bethesda is happy enough with TES Online and leaves TES 6 just as the other titles are ~ single player.
Delphine? I got back to her long enough to grab a Blade's sword, but got lost looking for Esbern in the ratway. I might head back there soon...Mjoll and I are currently going back to clean out Mzulft. I have a very strict "no leaving any goodies behind" policy. No rush...
.
I don't have the SE version of Skyrim so I haven't played any of the DLC...I thought I'd wait until I got good and tired of the vanilla game...and then splurge. I hope at least some of it is worth it.
Best,
Liquid Cool
