Heroes Gone Wild!
A great thing about GURPS is that its skill list covers not only classic adventuring tasks like combat, covert ops, and unsafe driving, but also social interactions, sciences, parrot-training, basket-weaving . . . And now, thanks to this new supplement, GURPS comes with options that can enhance certain action-oriented playing styles: wildcard skills that modify character sheets by replacing many standard skills.
