I wonder if the copyright/trademark lawyers are going to bite on this considering these monsters are pretty close rip offs of the original Universal monsters. Like direct copies of the Bela Lugosi, Lon Chaney and Boris Karloff characters that Universal owns.
When I created my monster deck I specifically went with generic monsters to avoid the nonsense that happened with The Army Men Deck. Plus I also requested info from Universal on this matter and I was told that the characters from the movies are still protected and owned by Universal. Going through the process to use the actual monsters in the Universal franchise was going to be a long and expensive process.
Hopefully they have covered their butts.
