I agree that table tennis and badminton are niche sports, though really good play of either is fun to watch. Personally, I get bored sooner watching tennis, but everyone prefers different things.
I haven’t played badminton since I was a kid in the backyard myself. Played table tennis for quite a few years but was never all that good, and now my hands have slowed down a lot. Even at my best, I played guys (and some women, too) who could spot me 18 points and the starting serve and beat me to 21 every time.
i got fairly good at it- had a fella in college who was unbeatable- i played against him for quite awhile- i got pretty good at hitting the edge of the table and just rolling the ball over the net- but never could win against him- he was always up for the challenge though- the game was more fun for him when winning lol
