One of my first exposures to Victorian era gaming was through the Ravenloft: Masque of the Red Death.
Last year I did Ravenloft, and this year given all the Victorian games I am talking about this seems a natural.
Masque of the Red Death was a Ravenloft branded supplement for both AD&D 2nd Ed and for D&D 3. Both dealt with a familiar; Earth, but one that was darker and magic was real. It's almost a cliche with me anymore. What made the first MotRD special was that for the first time you could play "D&D on Earth", in particular Victorian Age Earth that they called "Gothic Earth".
There were a lot of classes (kits too for AD&D 2nd Ed) and I always thought it was some what overkill. Magic was much more limited than your typical D&D game and a lot of the rules (Horror, Fear and Dread) were ported over from the Ravenloft line proper.
I SOOOO wanted to run this game, but it came at a bad time in my gaming career. I was just about ready to give up on D&D altogether and this was the only thing I was excited about anymore. Some of my first writing gigs was for the official Ravenloft Netbooks from the Kargatane. A lot of that I have been able to re-use here in fact (Haunted Illinois and the Piasa Bird).
There was such a cool, dark vibe to the game but it did do somethings that irked me. To many of the bad guys were in fact monsters that looked human; Moriarty was a Rakshasa for example. Sometimes I like my monsters to be human. Also there were just too many classes.
I'd love to revisit Gothic Earth. Maybe under one of the game systems I have reviewed already or even as something for Ghosts of Albion.
Sadly, Masque of the Red Death is long out of print. You can still find copies though on ebay and at Nobel Knight.
