It seems that in most games/sports, the better you become the less you play. In golf, for example, the better you are the fewer shots you take. In a race, the faster you are the shorter you are out there. In billiards (or 8-ball or 9-ball or straight pool) the better you are the fewer shots you’ll need to take.
I’m wondering what games or sports are out there in which the better you are the longer you play. I thought of pinball, where if you were a pinball wizard you might play forever. It goes both ways in video games. If you are really good at Mario Bros, you might finish the entire thing in a few hours. On the other hand, some games like Tetris you could play until your fingers fall off. Bull riding sort of fits, but in that case I think there is something like an 8 sec max regardless.
