Hi Nick,
Do whatever you please, and that is fun to play with. We positively encourage you to create your own companies, and there is an article on the blog to show you how.
As a heads up; Heroes, Villains and Fiends takes us out of the backstreets of old London Town and into Europe, Africa and the New World. So here are the lists for North America that will be in it:
The Apache (and allied tribes)
The Industrialists (Railroad Barons and the like)
The League of Southern Gentlemen
The Royal Northwest Mounted Police (Mounties)
The Red Sect (Louisiana Voodoo Cultists)
The High Sierra Gang, consisting of:
- The Virginians (classic post civil war outlaws)
- Las Diablos (Commancheros)
- The Golden Wheel (Gambling Saloon)
- The Pale Riders (remember A Town Called Hell?)
Mexican Federales Enforcement Co.
Mexican Rebels (led by El Toro!)
The Texas Rangers
The Secret Service
So that's thirteen lists for you to mad with in the Wild, Wild West
