I'm probably at 20 hours and still in act 1. I did most of the above stuff and some in the Underdark, but not Grymforge yet.
I'm playing with my first character, the halfling bard/lock. I was adamant to play the first time with her. THe reason, I'm not that far in is, that I was on vacation, when the game came out, so I started a bit later.
So far, I having a blast, my girl is romancing Shadowheart, friendly with everyone, though Astarion is on the verge between neutral and fair and I like most of it so far. I had a few crashs, but it seems, I had to only clear one folder, I forgot to clear, after I deinstalled EA.
