Thank you good sir, I will get right to it.
I would also like to add the following suggestions for miniatures that I had in mind for some of the companies.
Skaven - GW Skaven range, obviously
Metal Men from Deep Space - Hydra Miniatures' Robot Legion line is what I based this company on, but some of the Covenant of Antarctica Robots for Dystopian Legions would also work.
The Devil's Army - Some of the units I was inspired by Khurasan Miniatures Apoc666 Line and the 15mm Eldritch Horror minis. For the succubi, you can either use Helldirado Succubi or Mantic Miniatures (which has some other interesting demon figs in their lineup)
You'll have to do a bit of creative conversions for the rest.
Just thought I put that out there if anyone decides to play some of the companies that I created in their own games.
