What >> published << Blackmoor clones are out there?

[Havard]

Blackmarsh, but also I would consider Greyhawk Blackmoor to be a Blackmoor knock-off. It clearly borrows ideas from the "real" Blackmoor. Maybe it being a mirror world would be a better description.

That is an interesting perspective! I think it is a bit different from what Rafe had in mind, but it could be included for completeness.

There's also various Frog Cult adventures that seem like Blackmoor in all but name. Fane of the Toad is one that comes to mind, IIRC.

Thanks for reminding me of these.

The Fane of St. Toad is an excellent tribute adventure.

How many Frog related products are there?
