Infinite Worlds Alt-History Supernature and Superscience

[whswhs]

When I think about it, the great majority of my campaigns, in GURPS and other systems, have had overtly fantastic elements; in particular, I run a lot of fantasy and supers.

I haven't made use of Infinite Worlds as a campaign frame. However, I've used GURPS Alternate Earths as inspiration for campaign ideas; in particular, I've actually run a campaign set in the Earth of the Chinese Empire in AE2. (I did some tweaking based on adopting the 19th century British Empire as a model for the Chinese Empire; for one thing, I had England as a princely state.) I didn't feel any need to have supernatural or superscience elements to make the setting interesting. I did have martial arts, and worked out a dozen or so new schools of martial arts to fit the timeline. The campaign was intentionally cinematic in style and that seemed quite sufficient to make things interesting.
