Huh.
People apparently hating on Throne of Bhaal is news to me, honestly. I always thought it to be a really solid conclusion of the Bhaalspawn saga that nicely ties together the mess that started because Daddy Bhaal couldn't hold himself back and concludes every companion's story in a satisfying manner. And you got to hang out with a certain someone as a party member if you so desired, which was a really cool detail. My two big gripes with it were the fire giant area and the monk battle, but otherwise I had even had enjoyment figuring out how to actually kill Demogorgon and the like with a suboptimal party.
