It’s also a much more obscure game, my parents have a copy of it (so I played it many times in my childhood) but I’ve never encountered anyone else with one.

Also we usually didn’t call it by its German name “Was soll ich mich sorgen? Mach du dir Sorgen!” (more or less a direct translation of the above English), but just called it the “Selbstverteidigungskarte” (self-defense card).
