What are some wildcat RPG games?

It's a bit hard to define "wildcat" RPG games without more context! Do you mean:

* Games with unique and unusual mechanics: This could be anything from a system that uses playing cards to resolve actions, to a game with a focus on narrative instead of combat.

* Games with unconventional themes: This might include games about specific historical periods, strange fictional worlds, or very niche themes like urban fantasy or political intrigue.

* Games that are "underground" or less well-known: These might be self-published games, older games that are hard to find, or simply games that haven't gained widespread popularity.

To give you a better list, I need a little more information. Tell me:

1. What are you looking for in a "wildcat" RPG? Are you interested in specific mechanics, themes, or overall style?

2. What kind of RPG experience are you looking for? Do you want something light and comedic, dark and gritty, or something in between?

3. What are some of your favorite RPGs? This will help me understand your preferences and suggest something similar.

Once I know what you're looking for, I can give you some specific recommendations.
