No, but only because I feel it would lessen the wonder of my first playthrough in the final release; so it's not a fault on the part of Larian.
I avoided the EA for ages but in the end, as the years went by and with no concrete release date (and knowing how some games get delayed again and again), I finally caved and played about a year ago. I told myself it would just be for a couple of hours to get a feel for what it would be like but I loved it so much I played way more. I finally managed to reign myself in my just before reaching the Underdark.
I really hope the game is as long as they say it is as I'd be really annoyed with my lack of self control if I thought I'd played pretty much a third or quarter of the game.
