I'll detail this more, but wanted to share this now.
I am going back to the Tomb of Horrors.
I got the new Dungeons of Dread today.
Here is the history of my S4 collections.
Back coverleaf (not the cover itself).
My hardbound editions. Yes that is a hardbound version of Realms of Horror which was out in 87. No you didn't miss out on something, it was only softcover. I had it hardbound at a local book boundary.
The 87 Realms of Horror was a redo, the new Dungeons of Dread is the original modules in presentation.
The last is the 4th Ed update of Tomb of Horrors.
Again. More later.
