My immediate family used to have a pretty decently sized group of friends, and as luck would have it, pretty much every one of them was gaming. All this coincided with the existence of the SEGA Dreamcast. Actually a very good console, and it has a couple of excellent games. When all these friends came over, or we went out to them, we'd play some Dreamcast local multiplayer and one of the games we played a lot was 'Virtua Tennis'.
Virtua Tennis is fun because it's such an accessible game with fluid and intuitive controls, yet it still feels like a very realistic game. Like most Dreamcast games, the graphics were great. The game also has a fun career mode where you play across multiple locations on different surfaces trying to become the number one. In between those there are training stages where you must use special shots to hit things, stages that test your reaction time or stages for some other skill based task. Sports games normally don't turn my head, but once a century, one comes along that actually clicks.
