I really enjoyed my playtest. It's around 30 hours for the first act -- the game's probably about 90 hours long. That's pretty good considering I bought Jedi Fallen Order, and it was only 40 hours, same as Zelda Breath of the Wild.
I have read here that the part we have to play is act 1 A and that the tower you are traveling to is Act 1 B. Then Baldur’s Gate would be Act 2 and I would presume at least a part of Act 3 would return to Avernus. I think it is safe to bet that your first playthrough of the game will exceed 90 hours. My first playthrough of DOS2 was 110 hours, and Larian has indicated this game is bigger.
