There is a trend on various map subreddits to post about the counties you have visited, and can be split by merely driving through, staying the night, or whatever other criteria one wants to make. This subdividing is a significant improvement over the number of countries one has visited, and often results in more complicated logistics. Landing in an airport and visiting a major city is fun, but really getting out and driving (or biking) through the country is such a more enriching experience.
This even gets expanded further as people try to bike or run every road within their city or neighborhood or county, etc. Biking or running down an unfamiliar road is one of the treats of a day, and it is much easier, and often more enjoyable, than trying to make an excursion to a different country just to get the bragging rights (and possibly a passport stamp). As the world becomes more virtual and accessible, it is the alleys and farm roads that become more compelling to round out the places you have been.
I am curious if the world will go back to overtourism after travel restrictions are eased, but I hope that I turn away from the popular attractions and focus on visiting places where I have no connection just to walk and run and explore. Even on recent trips in well-known cities, I stopped going to well-known attractions, where one normally needs a pass in advance just to fight the crowds after waiting in line. It is much more enjoyable to find a strange museum off the beaten path, spend all morning walking there and all afternoon walking a different way back.
Ultimately, visiting the most places is not a contest based on subdivisions, but based on experiences. Large museums and famous parks are wonderful, but some of the best exhibits I have seen were in small cities and a random grove can make for a lovely place to camp. Seeking out a place because you have not been to that particular subdivision is nice, but seeking out a place because you have not been to that particular spot is just as wonderful.
