I have to say I really like these "what if" scenarios, and I was thinking of doing one myself. I'm sorry I haven't downloaded either one (Sarevok's or Azale's) so I can't give feedback on either one, although I probably will sometime in the future.
Again, I'm sorry I can't give feedback but I would like to know what you guys would think of a scenario like this: The Romans never had access to an Iron source in Italy, and never expanded past the Alps. The scenario would be set in the Industrial Age, in a very different world from nowadays.
