Amazing Roleplaying Engine is included. They had to. A.R.E. is a universal system, and this is the first universal scenario pack/campaign I have ever seen. Sci-fi, fantasy, steampunk, flying oil powered train engines, real science, mad science, xeno-science, elves, space aliens, magic, WW2, Hollow Earth, Atlantis, conspiracy theories, Lovecraft Horrors. I must admit the pictures from really cheezy thirties and fourties serials fit nicely.
