Traveler's Century Club: Something similar just for Europe?

Yesterday I heard for the first time about the Traveler's Century Club.

To become a member of this club you have to visit 100 or more countries. Although I'm not really interested in joining such a club, I'm curious if there is a similar club for European countries. So let's say you can become a member if you have visited 80% of all European countries.

I couldn't find something like this.
