My first CRPG, and my only RPG had been D&D.
My dad ran a campaign for our family when I was seven or so. Original D&D, not even advanced. It didn’t last terribly long but left a lifelong impression.
I recently inserted Creeping Coins to my Curse of Strahd campaign, as a matter of fact.
It was an unpopular twist, despite the group carrying a fortune in cursed money and having nothing whatsoever to spend it on.
That deserves its own sequel.
