Mostly:
On my second week of play now, and I've been spending most of my time on Guild quests and exploring the bottom half of Vvardenfell. I honestly haven't even done anything in the plot, outside joining the Blades, and I'm really not in any rush to change that fact.
As for character info: I'm playing a Redguard, Custom Class (Melee focus, with Armorer, Security, and Alchemy backing), and I just hit Level 38. Maxed Strength, maxed Long Blade, and nearly maxed Agility & Endurance (in the mid-to-high 80s). I also have a bunch of other skills in the 60-80 range, most notably Block, Heavy Armor, and Speechcraft. Great set-up for the most part, save for my Minor Skill choice of Sneak, as it's been completely useless thus far.
Anyway, I'm enjoying it quite a bit, and since it's such a freaking time-sink, I'm sure I'll be playing it for another month or so.
Also:
Unfortunately, I haven't had too much time to play it thus far, and my connection crapped out on the only night I had to set aside for it.

Still, I'm hoping to get some time to dedicate to it this weekend... Fingers crossed.
