Aceterak makes another "dastardly tomb"? with the same green devil face and juggernaut?
Um, yes? He likes those designs. Puts them in all his favorite digs. Honestly, I presume it's just to have a nice tie in with the previous adventure. Some cool iconic stuff from the original. And it seems reasonable that if Acererak came up with the green devil face, he'd be willing to use it again.
At any rate, as I mentioned in the rest of my post, there appear to be many, many differences between this adventure and the Tomb of Horrors adventure. At worst, this is something of a 'sequel' with a recurring D&D villain.
But I'm not trying to sell you on it. If the presence of Acererak and his green devil face makes it too much of a rehash for you, then that's fine. Was just trying to point out that this wasn't just a remake of the original.
