I think this has something to do with these games not aging very well. I must add that I grew up at a time Boris Becker and Steffi Graf pushed Tennis to be one of the most favorite sports in Germany and despite not being very interested and rather playing real Badminton myself, there still was no way around it. I had Atari Real Sports Tennis in the eighties as I didn't own a NES back then and I played the shit out of it as a kid. Same goes for Real Sports Boxing. Anyway, Real Sports Tennis did't even feel bad back in the day. It was a graphical step up from Pong, that required a second player and it was hard to find people playing with me, even though I still enjoy it as one of the most flawless and condensed games ever. As a kid, those crude graphics in general were augmented by our phantasy and we often created role playing around them, something I think got lost along the way of video gaming. It was indeed the opportunity to interact with what's on your TV that gave a lot of mileage to us. Returning to those games, even the Hudson Tennis which I think is better, doesn't even work all that well for me as an old man who grew up on these things. So I think there was a time for these games, but it's just over. On the other hand I don't really enjoy recent Tennis games either. So it might as well be that I just prefer the gameplay of Pong, because Windjammers, that's just an expansion of the idea, is among my very favorites and I'm still sad the sequel never got a competitive online community.
