NES Game: Tennis (1983 Nintendo).
A sports tennis game from Nintendo. This game is not so bad at first. But it gets much harder especially at level 5 where the opponent gets so annoying as hell and can take hours to beat and eventually hurt your wrist. It was one of Nintendo's first game game ported to the Playchoice-10 and Vs. arcade system. Also probably the first console game to have an ending without being restarted from the beginning indefinitely. This was released in Japan in late 1983.
Featuring Mario as Tennis Referee.
